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.
