This change allows any downstream or otherwise consumer to easily override the new -fno-common default on a temporary basis without having to hack into src.sys.mk, and also makes it a bit easier to search for these specific cases where -fno-common must be overridden with -fcommon or else the build will fail. The gdb build, the only program requiring -fcommon on head/, is switched over as an example usage. It will need it on all branches, so this does not harm future mergability. MFC after: 3 days
