4.9-stable review patch. If anyone has any objections, please let me know.

commit cfd6ed4537a9e938fa76facecd4b9cd65b6d1563 upstream.
GCC 7 now warns when switch statements fall through implicitly, and with -Werror enabled in configure.ac, that makes these tools unbuildable.
We fix this by notifying the compiler that this particular case statement is meant to fall through.
