You guessed correctly, it is a Linux system. Sorry about that...

For some reason I have */lib for the 64-bit libs, */lib32 for 32-bit,
and */lib64 symlinked to */lib.

I tried exactly that, after building as much as I could. The command
and output are:
$ x86_64-unknown-linux-gnu-gcc-4.0.2 -o hello -m32 -L/lib32/ -v hello.c
