Joseph Myers 8116321f65 Fix libm feupdateenv namespace (bug 17748). 
Concluding the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feupdateenv by making it a weak alias for
__feupdateenv and making the affected code call __feupdateenv.

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).  Also tested for ARM
(soft-float) that the math.h linknamespace tests now pass.

	[BZ #17748]
	* include/fenv.h (__feupdateenv): Use libm_hidden_proto.
	* math/feupdateenv.c (__feupdateenv): Use libm_hidden_def.
	* sysdeps/aarch64/fpu/feupdateenv.c (feupdateenv): Rename to
	__feupdateenv and define as weak alias of __feupdateenv.  Use

	* sysdeps/sparc/fpu/feupdateenv.c (__feupdateenv): Use
	libm_hidden_def.
	* sysdeps/tile/math_private.h (__feupdateenv): New inline
	function.
