Hmmm.  Well, I would say that this should be pushed to mainline,
but I still think it could be improved a bit.

IMHO, the config question should be something like:
"Use cross-compiler defined by Makefile", instead of "Are you
using a crosscompiler".

My recommendation would be to apply my patch and drop the
last sentence.  Then you get the best of all worlds:
 - support for command line specification, if you use it
 - support for env. var specification, if you use it.
 - automatic prefix selection if you use this option
