gcc12: fix building foreign toolchain on aarch64-darwin

Browse source 
It seems that the patchset we apply to get some fixes for aarch64-darwin
support [0] breaks in unexpected ways when compiling a foreign toolchain [1].
Luckily, according to the branch's author, the patchset isn't required
for merely using aarch64-darwin as the build system [2], so let's only apply
it when hostPlatform == aarch64-darwin to fix cross.
