Joseph Myers 01238691bb Fix libm fesetround namespace (bug 17748). 
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of fesetround by making it a weak alias of
__fesetround and making the affected code call __fesetround.  An
existing __fesetround function in fenv_libc.h for powerpc is renamed
to __fesetround_inline.

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

	[BZ #17748]
	* include/fenv.h (__fesetround): Declare.  Use libm_hidden_proto.
