One instance of this error/warning comes up during the build.
According to the comment in the code they know what they are doing,
so this can be ignored.
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 transmission conflict was non-trivial:
- libbrotli added to apparmor rules <1bdda029cd>
- apparmor rules rewritten <b280e64078>
Chosen the rewrite and verified that brotli is part of the rule set generated by `apparmorRulesFromClosure`.
Also begin to start work on cross compilation, though that will have to
be finished later.
The patches are based on the first version of
https://reviews.llvm.org/D99484. It's very annoying to do the
back-porting but the review has uncovered nothing super major so I'm
fine sticking with what I've got.
Beyond making the outputs work, I also strove to re-sync the packages,
as they have been drifting pointlessly apart for some time.

Other misc notes, highly incomplete
- lvm-config-native and llvm-config are put in `dev` because they are
tools just for build time.
- Clang no longer has an lld dep. That was introduced in
db29857eb3, but if clang needs help
finding lld when it is used we should just pass it flags / put in the
resource dir. Providing it at build time increases critical path
length for no good reason.
----
A note on `nativeCC`:
`stdenv` takes tools from the previous stage, so:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.stdenv.cc`: `(?0, ?1, x)`
while:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.targetPackages`: `(x, x, ?2)`
3. `pkgsBuildBuild.targetPackages.stdenv.cc`: `(?1, x, x)`
On other OSes, like NetBSD, these are part of libc. Fortunately, the
Lua Makefile already knows about this, and has a SYSLIBS variable we
can use for this.
We do this same patch in three different ways for four different Lua
versions, even though the structure of the Makefile barely changes
between releases. We can easily consolidate this by just modifying
the Makefile ourselves instead of using patches (Makefiles are very
amenable to this).
This is supposed to be automatically set by Lua's Makefile if PLAT is
set appropriately, but it was being overridden by us overridding
CFLAGS. Setting it manually was a hack. The correct thing to do was
to make sure SYSCFLAGS (where Lua's Makefile puts LUA_USE_LINUX) was
still included in our custom CFLAGS.
