Issue: sys-devel/gcc-11.3.1_p20230303 adds -Werror flag on its own.
Discovered on: amd64 (internal ref: ci)

NOTE:
-Werror is not recommended for releases and should always be disabled when encountered in build-logs, because there are numerous cases where this breaks without purpose.

build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)

It looks like -Werror only appears when building libgfortran.
