The static curl program is gone, replaced by curl inside of the
bootstrap tools tarball. Also, we generate a .tar.xz archive rather
than .cpio.bz2, making the download smaller. The separate
{sh,cpio,mkdir,ln,bzip2} programs have been replaced by a single
busybox program.
Make thread disabling explicit. This changes the semantics of the perl
derivation, so on other platforms it may require setting
enableThreading = false
This commit doesn't change the derivation or out hash of stdenvLinux.
The stage3.extraAttrs.glibc argument was required for this whole build
procedure to correctly work and it was very-very hard to see why (the
comment said something about gcc47, but we're using gcc48 now).
This stage3.extraAttrs.glibc goes into stage3.stdenv.glibc after some
arg passing, and in pkgs/development/compiler/gcc an (stdenv ? glibc)
boolean expression decides to override /usr/include during the GCC
build.
All of our stages are built with glibc, so this refactoring moves this
repeating specification of glibc (once for gcc wrapper and once here for
extraAttrs) to stageFun, by getting rid of wrapGCC, as we were using
that in all of the stages anyways.
Incidentally it turned out, that this stdenv.glibc inconsistency caused
some random other stuff to behave differently:
- stage1.pkgs.perl has threading disabled,
- stage4.pkgs.coreutils (the production coreutils) has testing disabled.
Leave this historical accidents as they are in this commit, so the scope
of this commit can stay as a refactoring only, these issues will be
fixed in separate commits.

Use the new allowedRequisites feature in stdenvLinux.
This way we properly check that the end-result stdenv of the quite
complicated multi-stage stdenvLinux building procedure is sane, and only
depends on the stuff that we know about.
Alternative would be to just disallowRequisites bootstrapTools, which is
the most common offender, but we have had other offenders in the past.
For these checks to actually fire, you currently have to use nixUnstable,
as the necessary feature will be released in Nix 1.8.
Previously stdenv depended on two different zlibs and there was a third
one in the top-level package set for other purposes. This commit merges
all this zlibs to one.
Actually this have been committed once as 1f2b636, but then got lost
while resolving merge conflicts. Hopefully it survives this time.
The 82797f98f2917e164db8691b516ed7f354b40ff4 merge caused this
issue while trying to merge the staging refactorings with
the modular-stdenv feature branch.
The point here is that it's always possible to debug this staging
logic by using `nix-repl pkgs/stdenv/linux'. The modular-stdenv
change introduced the lib dependency, which we now default to
../../../lib.
No derivation or out hashes of stdenvLinux is changed by this commit.

Make stages explicit and generalize the pattern of having an stdenv and
a pkgs collection for all stages to a common stage generating function
called stageFun.
Rewrite all stage handling with this new function.
This commit doesn't change the outhash (or drvhash) of the stdenv.
Don't use default parameter values, to make the callsites more readable
and for easier debuggability/changability. Also reordered the
callsites' parameter ordering for consistency.
In the final stdenv don't repeat the name of the shell.

All the different stages of stdenv had the fetchurl inherited anyways,
so make this generic in stdenvBootFun.

Commit 986f36194650e2a41451cbfb9f29ce1c66a62df3 started to use
<nix/fetchurl.nix> to "download" the bootstrap binaries from the
Nixpkgs tree, using the file:/// scheme. This has really bad
consequences:
* It makes any derivation depend on the path of the Nixpkgs tree. So
evaluating a package will produce a different .drv file when run
from different locations. No wonder Hydra evaluation has been so
slow lately: for every Nixpkgs evaluation, it had to create tens of
thousands of .drv files, even if nothing had changed.
* It requires the builder to have file system access to the Nixpkgs
tree. So if your tree is in your home directory, the stdenv
bootstrap would probably fail.
So now the binaries are downloaded from tarballs.nixos.org.
Also dropped PowerPC "support".
Binutils nowadays contains ld.gold, which depends on libstdc++. So it
needs to be built with the new GCC rather than the one from
bootstrap-tools.
Issue #1469.
