a gcc-4.2.1 derivative from codesourcery (4.2-50) that I needed to compile
eglibc for e500 and that I tweaked to use it with CLFS and that I compiled
with --host=powerpc-linuxspe.  I now noticed that it still generates
spe insn's even when given '-mno-spe'.

I am now busy to retest with a vanilla powerpc-linuxspe-gcc-4.2.2 and
that seems to work fine.  I don't think, though, that it is able to compile
eglibc for e500.

Thanks for the attention, and sorry for the noise.
