    glibc: Disable Werror when building with debug options
    
    Since compiler does not optimize away a lot of stuff we end up with
    Werrors e.g.
    
    ./sysdeps/ieee754/flt-32/s_log1pf.c: In function '__log1pf':
    ../sysdeps/ieee754/flt-32/s_log1pf.c:114:22: error: 'c' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      114 |        + (k * ln2_lo + c))) - f);
          |          ~~~~~~~~~~~~^~~~
    
    which otherwise wont happen, so lets build with warnings-as-errors
    disabled in debug mode
    
    given we disable werror, now we don't have to restrict user to compile
    without -O0
