Subject: [PATCH] Don't use <fenv.h> on uClibc

The python-numpy code already has provisions to not use <fenv.h> when
not available. However, it uses __GLIBC__ to know whether fenv.h is
available or not, but uClibc defines __GLIBC__, so python-numpy thinks
fenv.h is available.

This patch fixes that by changing all defined(__GLIBC__) occurences by
(defined(__GLIBC__) && !defined(__UCLIBC__)).
