 As I wrote an other mail, <mips/fenv.h> always has fegetround()
 (and other fe*() functions) as static inline functions:
 https://github.com/NetBSD/src/blob/trunk/sys/arch/mips/include/fenv.h 
 so I'm afraid __weak_reference(fegetround) will never referred on mips.
 (I'm not sure how __weak_reference() works in such static inline cases)
