You cannot build OpenBIOS with Apple's gcc 4.0.1. The 'gcc' installed  
by Xcode builds Mach-O binaries, not ELF binaries. You therefore need  
a cross-compiler and `./config/scripts/switcharch cross-ppc`.

I compiled the following in order, all of which were the latest stable  

GMP 4.3.1 - note: on ppc64 host supply ABI=mode32 to its configure  
script or it may build a 64-bit library that gcc later chokes on
MPFR 2.4.1
binutils 2.20
GCC 4.4.2

For GCC configure options please refer to Blue Swirl's post. I used -- 
target=powerpc-elf, but it was recently discussed whether -- 
target=powerpc-eabi is better or equal.
