I think it would be best to specify the cross-prefix at config time.
Guessing may get wrong results.

QEMU has nowadays a very clean configure vs. Makefile split (thanks to
Juan Quintela). Most if not all decisions are made at configure time,
Makefiles just use the CONFIG_xxx variables as told by configure. I'd
like to use a similar setup. Though QEMU does not have a deep
subdirectory layout which OpenBIOS has, that makes things easier for
them.
