powerpc: Use generic wcsrchr optimization
This patch removes the power6 wcsrchr optimization and uses generic implementation instead. Currently, both power6 and power7 IFUNC variant resulting binary are essentially the same and the generic implementation with unrolling loop set to 8 also results in similar performance. Checked on powerpc64-linux-gnu. * sysdeps/powerpc/Makefile [$(subdir) == wcsmbs] (CFLAGS-wcsrchr.c): New rule. * sysdeps/powerpc/power6/wcsrchr.c: Remove file. * sysdeps/powerpc/powerpc32/power4/multiarch/wcsrchr-power6.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcsrchr-power7.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcsrchr-ppc32.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcsrchr.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcsrchr-power6.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcsrchr-power7.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcsrchr-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcsrchr.c: Likewise. * sysdeps/powerpc/powerpc64/power6/wcsrchr.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/Makefile [$(subdir) == wcsmbs] (sysdeps_routines): Remove wcsrchr-power6 and wcsrchr-power7. (CFLAGS-wcsrchr-power7.c, CFLAGS-wcsrchr-power6.c): Remove rule. * sysdeps/powerpc/powerpc64/multiarch/Makefile: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/ifunc-impl-list.c: Remove wcsrchr optimizations. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c: Likewise.
