Reason:
- boehmgc_766 (pkgs/top-level/all-packages.nix) is only defined but not
used in Nixpkgs, so dropping it will not affect any package in Nixpkgs.
It was introduced for the asymptote package which has moved on to the
regular boehmgc attribute. There's a slim chance that some user depends
on it, but it would be unrealistic to expect us to maintain the
attribute indefinitely.
Details:
- Delete pkgs/development/libraries/boehm-gc/7.6.6.nix
- Delete pkgs/development/libraries/boehm-gc/riscv.patch
This round is without the systemd CVE,
as we don't have binaries for that yet.
BTW, I just ignore darwin binaries these days,
as I'd have to wait for weeks for them.
The configure script can't detect whether C11 atomic intrinsics are available
when cross-compiling, so it links to libatomic_ops, which has to be propagated
to all dependencies. To avoid this, assume that the atomic intrinsics are
available.
Fixes#43015 for me and hopefully also similar issues.

TL;DR: no change for small-memory cases, less CPU for large-memory cases.
I assume almost all of the large memory usage is just the expression
evaluation and managed by the GC, so I used just `nix-env -q...` to test.
Old and new lines for each command follow. I tried to run each several
times, but the values were very stable (<1% difference on re-runs),
so only one line for each command-version pair is provided.

In anticipation of what I outline in #33599, I only simplify exactly those
`doCheck`s which are equal to `hostPlatform != buildPlatform`. I also stick a
comment next to them so I can grep for them later.
- there were many easy merge conflicts
- cc-wrapper needed nontrivial changes
Many other problems might've been created by interaction of the branches,
but stdenv and a few other packages build fine now.
