* elf/check-textrel.c: Include config.h. (AB(handle_file)): Don't fail if PF_X | PF_W on architectures known to have executable writable PLT. * sysdeps/powerpc/powerpc32/configure.in (HAVE_PPC_SECURE_PLT): New test. * config.h.in (HAVE_PPC_SECURE_PLT): Add. * malloc/malloc.c (MALLOC_ALIGNMENT): Set to __alignof__ (long double) if long double is more aligned than 2 * SIZE_SZ. (misaligned_chunk): Define. (public_rEALLOc, _int_free, _int_realloc): Use it.
