sparc: refactor sparc64 __mpn_sub_n 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 sub_n-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines): Add sub_n-generic. * sysdeps/sparc/sparc64/multiarch/sub_n-generic.S: New file. * sysdeps/sparc/sparc64/multiarch/sub_n.c: Likewise. * sysdeps/sparc/sparc64/multiarch/sub_n.S: Remove file.
