sparc: refactor sparc32 copysign selector to C
This patch refactors the sparc32 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
s_copysign{f}-generic.S).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile
(sysdep_calls): New rule.
(sysdep_routines): Use sysdep_calls as base.
(libm-sysdep_routines): Add generic rule for symbols shared with
libc. Add s_copysign-generic and s_copysign-generic objects.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign-generic.S:
New file.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign.c: Likewise.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf-generic.S:
