Excellent.  I think this is simple enough to go into a new release, since
if it fixes the problem for you it will make cross-compilation work.
It didn't break anything that wasn't already broken.  Fixing those other
already broken things should be postponed till after the release.

That's a bug then, since the build uses prefix/suffixes.  If it's not
supported, that should be eliminated in normal host builds.
If it is supported, it should be fixed.

I'm looking at 897684c785e9c50a7b2a615f2963511c9aba23ef, which is
the latest master (4.7.5).

Sounds good.  Then we can file a Trac ticket so we don't forget about it.
