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
