+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__)).
