This is an additional fix for clang 16, which fails due to an undeclared
symbol. Adding `_DNS_SD_LIBDISPATCH` makes the symbol visible in
`dns_sd.h`, allowing the build to complete successfully.
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.

Revert a revert of a merge that shouldn't have been in master but was intentionally in staging.
Next time I'll do this right after the revert instead of so far down the line...
This reverts commit 9adad8612b.
I can't submit this in smaller units because the various components all
depend on one another during the stdenv bootstrap, so I think this is
the smallest sensible change I can make.
I also removed the symbol-hiding shenanigans in Libsystem. It might mess
up compatibility with 10.9 but I don't really want to support the added
complexity and I see little evidence of anyone else wanting to support
it. If someone cares, we might be able to revive compatibility, but for
now it'll stay like this.
