commit b4f518ecfad09fc4279ea26a565332835e403dab
Author: Carlos O'Donell <carlos@redhat.com>
Date:   Tue Mar 15 23:16:47 2016 -0400

    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.
