Fix libm feholdexcept namespace (bug 17748).
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feholdexcept by making it a weak alias of
__feholdexcept and making the affected code call __feholdexcept.

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

	[BZ #17748]
	* include/fenv.h (__feholdexcept): Declare.  Use
	libm_hidden_proto.
	* math/feholdexcpt.c (feholdexcept): Rename to __feholdexcept and
	define as weak alias of __feholdexcept.  Use libm_hidden_weak.
