extra_compile_args is not used by numpy, its to support some third party

As the typical site.cfg used by numpy only contains binaries that are

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)
