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. * math/fesetround.c (fesetround): Rename to __fesetround and define as weak alias of __fesetround. Use libm_hidden_weak. * sysdeps/aarch64/fpu/fesetround.c (fesetround): Likewise. * sysdeps/alpha/fpu/fesetround.c (fesetround): Likewise. * sysdeps/arm/fesetround.c (fesetround): Likewise. * sysdeps/hppa/fpu/fesetround.c (fesetround): Likewise. * sysdeps/i386/fpu/fesetround.c (fesetround): Likewise. * sysdeps/ia64/fpu/fesetround.c (fesetround): Likewise. * sysdeps/m68k/fpu/fesetround.c (fesetround): Likewise. * sysdeps/mips/fpu/fesetround.c (fesetround): Likewise. * sysdeps/powerpc/fpu/fenv_libc.h (__fesetround): Rename to __fesetround_inline. * sysdeps/powerpc/fpu/fenv_private.h (libc_fesetround_ppc): Call __fesetround_inline instead of __fesetround. * sysdeps/powerpc/fpu/fesetround.c (fesetround): Rename to __fesetround and define as weak alias of __fesetround.
