extra_compile_args is not used by numpy, its to support some third party 
use case I never understood.
As the typical site.cfg used by numpy only contains binaries that are 
never compiled by numpy itself it should have no effect on anything.

still seems to work for me, though the preferred variable is OPT= as 
CFLAGS will contain a bunch of other stuff related to building python 
extensions themselves (e.g. -fno-strict-aliasing)
