* sysdeps/unix/sysv/linux/powerpc/libc-start.c (__cache_line_size): Define the variable here. Add attribute_hidden, remove weak_extern. (__libc_start_main): Set __cache_line_size unconditionally. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c (__cache_line_size): Define the variable here. Add attribute_hidden, remove weak_extern. (DL_PLATFORM_AUXV): Set __cache_line_size unconditionally. * sysdeps/powerpc/powerpc32/dl-machine.c (__cache_line_size): Remove weak_extern, add attribute_hidden. (__elf_machine_runtime_setup): Assume __cache_line_size is always defined in ld.so. * sysdeps/powerpc/powerpc32/memset.S (__cache_line_size): Remove definition. * sysdeps/powerpc/powerpc64/memset.S (__cache_line_size): Likewise.
