package/glibc: disable Werror for gcc 10 build
Currently glibc 2.30 is build by default with Werror enabled but it has only been tested with compiler version available at the time of the release [1] (gcc 6.2 up to gcc 9.2.1). It's recommended to use those version with glibc 2.30. For the same reason why we remove Werror in packages's compiler flags. Building with Werror is not bulletproof when we start using a newer compiler that introduce new warnings. This is the case here with gcc 10, as reported by Yegor Yefremov [2]. Fixing compiler warnings would require backporting many patches [3] not even backported by Glibc maintainers to the 2.30 stable branch. Instead, disable Werror by using --disable-werror. Most (if not all) gcc 10 warnings will be fixed with Glibc 2.31.
