I think this was a rebase mishap and causes a ton of rebuilds.
Not sure if we actually need the Darwin condition any more (or to be
using the older `isl` version?), but `master` isn’t the place to
find out :)

# do not allow version skew when cross-building gcc
|
|
#
|
|
# When `gcc` is cross-built (`build` != `target` && `host` == `target`)
|
|
# `gcc` assumes that it has a compatible cross-compiler in the environment
|
|
# that can build target libraries. Version of a cross-compiler has to
|
|
# match the compiler being cross-built as libraries frequently use fresh
|
|
# compiler features, like `-std=c++26` or target-specific types like
|
|
# `_Bfloat16`.
|
|
# Version mismatch causes build failures like:
|
|
# https://github.com/NixOS/nixpkgs/issues/351905
|
|
#
|
|
# Similar problems (but on a smaller scale) happen when a `gcc`
|
|
# cross-compiler is built (`build` == `host` && `host` != `target`) built
|
|
# by a mismatching version of a native compiler (`build` == `host` &&
|
|
# `host` == `target`).
|
|
#
|
|
# Let's fix both problems by requiring the same compiler version for
|
|
# cross-case.
