libgit2 didn't write thin ones, hence the patch.
This should improve performance on systems with weak I/O in ~/.cache,
especially in terms of operations per second, or where system calls
are slower. (macOS, VMs?)
As discussed in our meeting, we should use a simplified version for the
libraries without the date or commit hash. This will make rebuilding a
lot faster in many cases.
Progress on #10379

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.
