Fix libm fesetenv namespace (bug 17748).

Browse Source 
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of fesetenv by making it a weak alias of
__fesetenv and making the affected code (including various copies of
feupdateenv which also gets called from C90 functions) call
__fesetenv.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).  Also tested for ARM
(soft-float) that fesetenv failures disappear from the linknamespace
test results (fsetround and feupdateenv remain to be addressed to
complete fixing bug 17748).

	[BZ #17748]
	* include/fenv.h (__fesetenv): Use libm_hidden_proto.
	* math/fesetenv.c (__fesetenv): Use libm_hidden_def.
