There are a number of additional check that are performed and the resulting warnings are treated as errors causing the RPM build to fail.  The build log for x86_64 (https://kojipkgs.fedoraproject.org//work/tasks/894/17680894/build.log) shows a number of warning/errors for "-Wimplicit-fallthrough".  SystemTap had a similar issue that was fixed (https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commit;h=575fe913f6b6b81421f7bfda7c72ab8c15ecb8e3).

There is some information about porting to gcc 7 at:
