lib.systems.inspect.patterns.isEfi: drop ARMv5
I'm not aware of any ARMv5 EFI implementation.  gnu-efi doesn't
support it, so the build of systemd for armv5tel-linux is broken if
it's isEfi.

lib.systems.inspect.patterns.isEfi: remove "aarch64"
There is no "aarch64" CPU family — it counts as "arm", as can be seen
from the definition of isAarch64 above.

Checked that stdenv.hostPlatform.isEfi is still true on aarch64-linux.

14f337afb6 lib/systems/inspect.nix: add isILP32 predicate
I've run into a few packages that need an extra flag on platforms
where `int` has more bits than `void*` does.  I know of three such
platforms:

* [aarch64ilp32], used on both Linux and also on the [Apple Watch]
* [x32], the x86 ILP32 ABI
* [mips64n32], used on [Longsoon] and Cavium Octeon routers.

This PR introduces a predicate so the package flags can be added in
a generic way.

de88969f12 lib/systems: fix uname.processor for powerpc{32,64}, mips64
Cross-compilation of anything downstream of gtk3 requires qemu (due to
gobject-introspection) with --target-list=*-linux-user.  Without this commit,
those qemu builds will fail on a powerpc64le host due to qemu being configured
with --cpu=powerpc64le instead of --cpu=ppc64le.  Unfortunately the build
failure message from qemu in this situation is extremely cryptic.

The root cause turns out not to be the qemu expression, but rather the fact that
on powerpc64le hostPlatform.uname.processor returns the gnu-name (powerpc64le)
for the cpu instead of the linux-name (ppc64le) for the cpu.

uname.processor on mips64el also needs adjustment -- the Linux-name is "mips64"
for both big and little endian (unlike powerpc64, where the Linux-name includes
a "le" suffix):

```
nix@oak:/tmp$ uname -m; lscpu | head -n2
mips64
Architecture:        mips64
Byte Order:          Little Endian
```

uname.processor on powerpc32 has also been adjusted.

36a566b78f lib/systems/parse.nix: mkSkeletonFromList: improve readability
The main purpose of this PR is to make the basis for
`mkSkeletonFromList`'s decision between `cpu-kernel-libcabi` vs
`cpu-vendor-os` clear, without changing its behavior.  The existing
code obscures this decision behind a sequence of prioritized matches
(i.e. `if-then`) which jump around between different coordinates.

Two side benefits of this PR:

1. It makes the root cause of #165836 obvious: we are missing a case
   for `cpu-vendor-libcabi`.  This is why nixpkgs stumbles over
   `*-none-*`.

2. It illuminates some very weird corner cases in the existing
   logic, like `*-${vendor}-ghcjs` overriding the `vendor` field,
   and `mingw32` being transformed into `windows` in some cases.

66aa02f190 lib/systems: Support FreeBSD
A tricky thing about FreeBSD is that there is no stable ABI across
versions. That means that putting in the version as part of the config
string is paramount.

We have a parsed represenation that separates name versus version to
accomplish this. We include FreeBSD versions 12 and 13 to demonstrate
how it works.

lib/systems: uname.processor is "uname -m", not "uname -p" (#189958)
The comment in lib/systems/default.nix for uname.processor indicates that it
should match `uname -p`.  I tried that command and found that it reports
`unknown` on all of these machines:

- `x86_64-linux`
- `aarch64-linux`
- `mips64el-linux`
- `powerpc64le-linux`

The command `uname -m` reports the expected value on all of the above.

I think the comment is wrong.  So I fixed it.

e8d7d52fae lib.systems.examples: canonicalize MIPS triples
In Nixpkgs, we assume that the "config" field is a canonicalized GNU
triple.  I noticed that non-canonical values were being used here,
because the pkgsCross.mips64el-linux-gnu triples did not contain the
vendor field, but the pkgsCross.mips64el-linux-gnu.pkgsStatic did.

Here, I've run all the MIPS triples in lib.systems.examples through
config.sub to canonicalize them.  I think this will avoid nasty
surprises in future.

Tested by building Nix and the bootstrap files for
pkgsCross.mips64el-linux-gnu.

c0085404bd lib/systems/inspect.nix: remove isPowerPC
Very confusingly, the `isPowerPC` predicate in
`lib/systems/inspect.nix` does *not* match `powerpc64le`!

This is because `isPowerPC` is defined as

  isPowerPC      = { cpu = cpuTypes.powerpc; };

Where `cpuTypes.powerpc` is:

  { bits = 32; significantByte = bigEndian; family = "power"; };

This means that the `isPowerPC` predicate actually only matches the
subset of machines marketed under this name which happen to be 32-bit
and running in big-endian mode which is equivalent to:

  with stdenv.hostPlatform; isPower && isBigEndian && is32bit

This seems like a sharp edge that people could easily cut themselves
on.  In fact, that has already happened: in
`linux/kernel/common-config.nix` there is a test which will always
fail:

  (stdenv.hostPlatform.isPowerPC && stdenv.hostPlatform.is64bit)

A more subtle case of the strict isPowerPC being used instead of the
moreg general isPower accidentally are the GHC expressions:

  Update pkgs/development/compilers/ghc/8.10.7.nix
  Update pkgs/development/compilers/ghc/8.8.4.nix
  Update pkgs/development/compilers/ghc/9.2.2.nix
  Update pkgs/development/compilers/ghc/9.0.2.nix
  Update pkgs/development/compilers/ghc/head.nix

Since the remaining legitimate use sites of isPowerPC are so few, remove
the isPowerPC predicate completely. The alternative expression above is
noted in the release notes as an alternative.

sternenseemann
acb063701a lib.systems.elaborate: expose canExecute predicate over isCompatible
canExecute is like isCompatible, but also checks that the Kernels are
_equal_, i.e. that both platforms use the same syscall interface. This
is crucial in order to actually be able to execute binaries for the
other platform.

isCompatible is dropped, since it has changed semantically and there's
no use case left in nixpkgs.

fe836f3564 lib/systems/parse: don't consider mode switching CPUs compatible
Since we (exclusively) use isCompatible to gauge whether platform a can
execute binaries built for platform b, mode switching CPUs are not to be
considered compatible for our purposes: Switching the mode of a CPU
usually requires a reset. At the very least we can't execute a mix of
executables for the two modes which would usually be the case in nixpkgs
where we may want to execute buildInputs for the hostPlatform in
addition to nativeBuildInputs for the buildPlatform.
