We (Adélie) do this on x86_64 and ppc64 arches already (both of them
have various gcc-* binutils-* etc). It would be cool if Alpine wanted
to do that. And necessary, if kernels are cross-built.

CARCH and CROSS_COMPILE makes sense, since they are used by abuild. CC,
CCACHE_*, and DISTCC_* make more sense in /etc/abuild.conf imo.

Yes, I personally think this is a bad idea and abuses the fact that
APKBUILD files are `source`d by abuild. It is better to remove from the
APKBUILD. I would even be in favour of having a little shell script in
the linux-vanilla package or such that takes CARCH and CROSS_COMPILE
like abuild does, and calls menuconfig properly for you. But not
directly from the APKBUILD.
