This causes the build to fail if there is a switch/case fallthrough.

Tested on x8_64-linux-gnu.  Built with build-many-glibcs.py (except for
sparcv8-linux-gnu-leon3 due to its unrelated failure).

Thanks,
Florian

  x86: Add missing switch/case fall-through markers to init_cpu_features
  x86: Tunables may incorrectly set Prefer_PMINUB_for_stringop (bug
    32047)
  nss: Fix incorrect switch fall-through in tst-nss-gai-actions
  Turn on -Wimplicit-fallthrough by default if available
