glibc: Enable -Werror for more combinations of GCC/GLIBC

Browse Source 
Newer GCC versions trigger warnings on older GLIBC versions. GLIBC 2.29
is warning free with GCC9. GLIBC 2.31 is warning free with GCC10. GLIBC
2.34 is warning free with GCC11.

Add milestones for 2.31 and 2.34 and use those to set the default value
for GLIBC_ENABLE_WERROR based on the GCC version.

By default, glibc enables strict warning checks during the build.
However, older version of glibc may not build with newer versions
