Sorry, it can't work, I am sure, because many details causing breakage
are hard-coded into redhat-rpm-config. Not even building cross-compilers
works correctly because redhat-rpm-config breaks things.
(Cf. avr-binutils's and avr-gcc's specs in Fedora).

And what is being produced? An *.i386.rpm or an *.arm.rpm?
