By syncing with Nixpkgs, we reuse the same derivation, which is
generally a good idea, and has the benefit that it is transitively
a channel blocker.
Changes:
- https://github.com/NixOS/nixpkgs/pull/163313 (SuperSandro2000)
> nix: disable big-parallel for aws-sdk-cpp
> aws-sdk-cpp only takes ~1m52s on a 4 core machine under 50% load
> which does not justify the requirement on big parallel.
> Tested with `nix-build -A nixVersions.nix_2_6.aws-sdk-cpp`.
> I can finally build nix without requiring a big-parallel machine.
- https://github.com/NixOS/nixpkgs/pull/227506 (Artturin)
> nix: use [ ] instead null to empty requiredSystemFeatures
> fixes 'error: value is null while a list was expected' with 'nixpkgs.hostPlatform.gcc.arch = "x86_64";'
In addition to adding the missing thread deps in the last commit, we
also appear to need to skip `-Wl,--as-needed` flags that Meson wants to
use, but doesn't work with our *BSD toolchains.

They are not actually part of the store layer, but instead part of the
Nix executable infra (libraries don't need plugins, executables do).
This is part of a larger project of moving all of our legacy settings
infra to libmain, and having the underlying libraries just have plain
configuration structs detached from any settings infra / UI layer.
Progress on #5638
GitHub Actions seems to have magically switched architectures
without changing their identifiers.
See 2813ee66cb/README.md (available-images)
Maybe they have more complete documentation elsewhere, but it
seems to be incapable of selecting a runner based on architecture.
This avoids polluting nixComponents with things that aren't our
components.
Fixes the extraction of passthru tests, which failed for boehmgc
which had many irrelevant ones anyway.
