sparc: refactor sparc64 nearbyint{f} selector to C
This patch refactors the sparc64 ifunc selector to a C implementation. Also, the generic symbol is moved to its own implementation file s_nearbyint{f}-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc64/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_nearbyint-generic and s_nearbyintf-generic objects. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyint-generic.S: New file. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyint.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyintf-generic.S: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyintf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyint.S: Remove file. * sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyintf.S: Likewise.
