This patch fixes the build of C mempcpy and stpcpy by disabling the redirection to __mempcpy and __stpcpy asm names if NO_MEMPCPY_STPCPY_REDIRECT is defined, and defining that macro in the relevant source files. Tested for powerpc32 that the build is fixed. * include/string.h [NO_MEMPCPY_STPCPY_REDIRECT] (mempcpy): Do not redeclare with asm name. [NO_MEMPCPY_STPCPY_REDIRECT] (stpcpy): Likewise. * string/mempcpy.c (NO_MEMPCPY_STPCPY_REDIRECT): Define before including <string.h>. * string/stpcpy.c (NO_MEMPCPY_STPCPY_REDIRECT): Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/mempcpy.c [!NOT_IN_libc] (NO_MEMPCPY_STPCPY_REDIRECT): Likewise. * sysdeps/powerpc/powerpc64/multiarch/mempcpy.c [!NOT_IN_libc] (NO_MEMPCPY_STPCPY_REDIRECT): Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpcpy.c [SHARED && !NOT_IN_libc] (NO_MEMPCPY_STPCPY_REDIRECT): Likewise.
