I'm trying to compile 32-bit numpy on a 64 bit Centos 6 system, but fails with the message:

this might work:
CC="gcc -m32" LDSHARED="gcc -m32" FF="gfortran -m32" linux32 python setup.py build
That didn't work. It says it can't find executable "gcc -m32". I tried changing ccompiler.py, per the stackoverflow post. I got further that time, but it fails with the message:
weird it works for me with libpython2.7-dev:i386 installed on amd64 Ubuntu 13.10 (multiarch is friggin great :D) But I had to add an additional LDFLAGS="-m32 -shared"
CC="gcc -m32" LDSHARED="gcc -m32 -shared" LDFLAGS="-m32 -shared" linux32 python setup.py build
you should be able to work around this error message by writing small wrapper scripts for the compiler:
cat << EOF > gcc-32 #!/bin/sh gcc -m32 "$@" EOF ... CC=gcc-32 ....
No luck. Here are my results:
bash~$ CC=gcc-32 LDSHARED=ld-32 LDFLAGS="-m32 -shared" linux32 python2.7 setup.py build

This makes no sense to me. The linker is set to 32 bit. My python library path is 32 bit. I know it can find the library, or the build wouldn't have even started.
