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: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf.S: Likewise.
