Clang 15 does not like the fake xpc headers. Use the real ones instead.
Doing this no longer causes an infinite recursion because xnu now
depends on python3Minimal, which does not include configd support.
`configd` is aliased to `apple-sdk.frameworks.SystemConfiguration` in
apple-sdk-11.0, which is the default on aarch64-darwin, but it does not
include all of the headers. This package introduces the missing
headers, which are needed to build `libresolv`.
A subsequent commit will fix libresolv to build on aarch64-darwin.
If things build fine with `stdenvNoCC`, let them use that. If tools
might be prefixed, prepare for that, either by directly splicing or just
using the env vars provided by the wrapper setup-hooks.

I am taking the non-invasive parts of #110914 to hopefully help out with #111988.
In particular:
- Use `lib.makeScopeWithSplicing` to make the `darwin` package set have
a proper `callPackage`.
- Adjust Darwin `stdenv`'s overlays keeping things from the previous
stage to not stick around too much.
- Expose `binutilsNoLibc` / `darwin.binutilsNoLibc` to hopefully get us
closer to a unified LLVM and GCC bootstrap.
The only outside-curl uses of `fetchurlBoot` left are `stdenv`
and `apple-source-releases`. The latter one can probably be removed
too, but I can't test it.
Pros:
- Aggregates all behind-the-scenes insanity in a single place.
Cons:
- At the cost of 10 more derivations (but 0 new outpaths).
LTO is disabled during bootstrap to keep the bootstrap tools small and
avoid unnecessary LLVM rebuilds, but is enabled in the final stdenv
stage and should be usable by normal packages.
This also updates the bootstrap tool builder to LLVM 5, but not the ones
we actually use for bootstrap. I'll make that change in a subsequent commit
so as to provide traceable provenance of the bootstrap tools.
Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.
This includes adding a new xcbuild-based libutil build to test the waters a bit there.
We'll need to get xcbuild into the stdenv bootstrap before we can make the main build,
but it's nice to see that it can work.
This wasn't being used and it was causing an error when evaluating:
