[PATCH 1/1] python-numpy: fix compile error for qemumips

[Chen Qi]

When building python-numpy for qemumips, the following error appeared.

cp: cannot stat `xxx/python-numpy/1.7.0-r1/*config.h': No such file or directory

This is because for qemumips, there are no such files in SRC_URI. And
actually we don't need such files. So for qemumips, the `cp' command
is expected to fail.

The same problem appeared for qemumips64 and qemuppc.

This patch fixes this compiling error.

Those files contain the definitions of things like word size and byte
ordering, so unless I've misunderstood the build process for numpy
what's happening with this patch is that it's using the host
environment.

Those files are there already.
For archs like x86, we first replace them so that the build process 
doesn't fail (according to the comments in the recipe); but for 
mips/ppc, we don't need to do so, the build just succeeds.

Ross' point stands, its just using the values from the host (build)
system. If your build system was mips it might stand a chance of
working, I suspect you're building on x86 though and x86 != mips.

Cheers,

Richard

Ross & Richard,

Thanks for making it clear.
Yesterday, I built it and tested it on target. As some basic tests 
passed, I thought everything was OK.
Now I've checked those files, and obviously I've made a mistake.
I'll rework on this one.

Best Regards,
Chen Qi
