cross-compiler intel -> powerpc-gnu-linux

[Bill Webster]

I recently conpleted a build of the cross compiler for ppc. I did not experience the same problem that
you seem to be having. I was having a problem with the linker (unsupported emulation). I was able to
finally resolve the problem by using binutils-2.9.5.0.46. I downloaded it from
ftp://ftp.varesearch.com/pub/support/hjl/binutils/ .
