I was able to get the glibc to build in a powerpc cross compilation
scenario, here is a patchfile I came up with that fixes another issue
that came up with libgcc_eh...This is basically hacking out the test
in the first place so this will break something else, specifically whatever
called for the altivec test in the first place.
