This would be reverting the fix for <http://bugs.gnu.org/22186> as the
comment above explains.

I suppose the problem is that CPATH is still used elsewhere, leading to
interference with this one.  However, the cross-compilers for
mips64el-linux-gnu and armhf-linux-gnueabi work fine, AFAIK.

Thoughts?
