This is a small patch that we (my partners and I) at Opencon (a newly
formed Brazilian Free Software/Open Source consulting firm,
opencon@rio.skydome.net) made to let people using RPM on non-x86
architectures to compile their kernel with 'make rpm'.
It simply hacks the shell script at /usr/src/linux/scripts/mkspec - it
it finds a x86, it issues a 'make bzImage' and acts accordingly; if not,
it issues a 'make vmlinux'.
It's a simple hack, so please test it, especially on other
architectures. It worked on my PowerMac 5500 and one of my friends'
iBook.

Have fun.

- Cesar
