build script and full log

I'm trying to cross-compile llvm-gcc for powerpc target on amd64/linux

The compilation stopped when compiling gcc/config/rs6000/rs6000.c

================== log fragment  end  ==========================

IMHO
1) MASK_MACHO_DYNAMIC_NO_PIC is not defined anywhere, though used twice. I
looked for it in the complete patch/build tree and in /usr/include

2) "#endif llvm" is present only in this file and breaks C rules and apple/llvm
coding style

3) Other errors are present

i enclose ebuild script and full log file

my aim is not to find lots of errors in llvm source code but to compile
PowerPC-capable llvm-gcc decompiler on my computer
