Hi

I am trying to do a cross platform build of numpy (host=x86 target=ppc). This worked for python compiler itself but for numpy I run into following problem.

It does select the correct compiler but the options are not correct. please advise...

 numpy-1.10.2rc2]$ CC=powerpc-e500v2-linux-gnuspe-gcc CXX=powerpc-e500v2-linux-gnuspe-g++ AR=powerpc-e500v2-linux-gnuspe-ar                            BLAS=None LAPACK=None ATLAS=None  python setup.py build  bdist_egg   --plat-name=powerpc
