GCC Built by ./build_gcc.sh o32-gcc and o32-g++ only target x86_64

[jlsantiago0]

The wrappers seem to be broken for i386 builds with GCC. I have tested with SDKs v10.11 and v10.13. All of the GCC tools only target x86_64. The clang tools work correctly.

This includes:

o32-gcc
o32-g++
i386-apple-darwinXX-gcc
i386-apple-darwinXX-g++
x86_64-apple-darwminXX-gcc -m32
x86_64-apple-darwminXX-g++ -m32

Tested with latest master and GCC-10.5.0 and GCC-12.3.0.
