23c520d95e cc-wrapper: only set -march when platform.gcc.arch is specified
We want to make sure this value is explicitly set. Infering it for
every arch leads to annoying failures like:

https://hydra.nixos.org/build/92583832/

Perhaps we can enable it in the future with some smarter handling of
cc-wrapper.sh.

9abff4af4f wasm: init cross target
Adds pkgsCross.wasm32 and pkgsCross.wasm64. Use it to build Nixpkgs
with a WebAssembly toolchain.

stdenv/cross: use static overlay on isWasm

isWasm doesn’t make sense dynamically linked.

d180cb9850 cc-wrapper: make machine configuration configurable
It is useful to make these dynamic and not bake them into gcc. This
means we don’t have to rebuild gcc to change these values. Instead, we
will pass cflags to gcc based on platform values. This was already
done hackily for android gcc (which is multi-target), but not for our
own gccs which are single target.

To accomplish this, we need to add a few things:

- add ‘arch’ to cpu
- add NIX_CFLAGS_COMPILE_BEFORE flag (goes before args)
- set -march everywhere
- set mcpu, mfpu, mmode, and mtune based on targetPlatform.gcc flags

cc-wrapper: only set -march when it is in the cpu type

Some architectures don’t have a good mapping of -march. For instance
POWER architecture doesn’t support the -march flag at all!

d453273fbf llvm8: support c++ in cross case
this adds libc++ to the LLVM cross, giving us access to the full
Nixpkgs set. This requires 4 stages of wrapped compilers:

- Clang with no libraries
- Clang with just compiler-rt
- Clang with Libc, and compiler-rt
- Clang with Libc++, Libc, and compiler-rt

77550df8e6 cc-wrapper: add libcxx for libcxxClang
clang needs to find headers + libraries for compiling with libc++. We
need to add a libcxx argument to cc-wrapper. This means you do not
have to pass in c++ headers directly.

This resolves the last case remaining of #30670. Darwin clang++ now
works properly.

Fixes #30670

d32f51c618 cc-wrapper, bintools-wrapper: simply symlink man and info outputs
With the previous commit `propagateDoc` is now always given the correct value
(i.e. it is never set to `true` when there are no `man` and `info` outputs).
Hence, we can simply symlink the original outputs to the wrapper outputs.

Pros:

- simpler, less indirection compared to `propagated-user-env-packages`,
- uses less inodes (1 symlink, which nix then simply automatically resolves
  and removes, vs. two directories and a file),
- makes direct references like "export MANPATH=${stdenv.cc.man}/share/man"
  simply work.

Cons:

- I'm not aware of any.

This and the previous commit together almost completely revert commits

412093994b gcc: support avr
- respect libc’s incdir and libdir
- make non-unix systems single threaded
- set LIMITS_H_TEST to false for avr
- misc updates to support new libc’s
- use multilib with avr

For threads we want to use:
- posix on unix systems
- win32 on windows
- single on everything else

For avr:
- add library directories for avrlibc
- to disable relro and bind
- avr5 should have precedence over avr3 - otherwise gcc uses the wrong one

b2c7a5a271 bintools-wrapper, cc-wrapper, stdenv: infer propagateDoc automatically
02c09e01712ce0b61e5c8f7159047699a434f7fc (NixOS/nixpkgs#44558) was reverted in
c981787db951afb11c1328461df82d4277ebec07 but, as it turns out, it fixed an issue
I didn't know about at the time: the values of `propagateDoc` options were
(and now again are) inconsistent with the underlying things those wrappers wrap
(see NixOS/nixpkgs#46119), which was (and now is) likely to produce more instances
of NixOS/nixpkgs#43547, if not now, then eventually as stdenv changes.

This patch (which is a simplified version of the original reverted patch) is the
simplest solution to this whole thing: it forces wrappers to directly inspect the
outputs of the things they are wrapping instead of making stdenv guess the correct
values.

330ca731e8 treewide: Get rid of all uses of crossConfig
The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)

Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:

 - bintools-wrapper and cc-wrapper
