sparc: refactor sparc64 __mpn_addmul_1 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
addmul_1-generic.S).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
Add addmul_1-generic.
* sysdeps/sparc/sparc64/multiarch/addmul_1-generic.S: New file.
* sysdeps/sparc/sparc64/multiarch/addmul_1.c: Likewise.
* sysdeps/sparc/sparc64/multiarch/addmul_1.S: Remove file.
