Fix building glibc master with NDEBUG and --with-cpu.
When building on i686, x86_64, and arm, and with NDEBUG, or --with-cpu there are various variables and functions which are unused based on these settings. This patch marks all such variables with __attribute__((unused)) to avoid the compiler warnings when building with the aformentioned options.
