[Numpy-discussion] cross platform build issue: powerpc-e500v2-linux-gnuspe-gcc: error: unrecognized argument in option '-mtune=generic'

[jo]

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...
