gcc14: fix build on aarch64-darwin
The previous patch didn't apply anymore for 14.3.0.
Currently there is no branch for 14.3.0 in https://github.com/iains/gcc-14-branch
nor in homebrew. This lead me to use the -pre branch with a custom target.

This patch was produced by manually merging:

* <https://github.com/iains/gcc-14-branch/tree/gcc-14.2-darwin-r2>

6

and then taking the diff between the result and the upstream GCC
7
-
commit, and excerpting only the files that have conflicts when
8
-
naively applying the branch’s diff to the snapshot. (This is
9
-
more files than the two that actually needed manual merge work –
10
-
`gcc/config/aarch64/aarch64-tune.md` and `libgcc/config.host` –
11
-
because `patch(1)` can’t do a three‐way merge using ancestor
12
-
information.)
