Something like this (before I make the same mistakes on the others):

Subject: [PATCH] nptl: Convert tst-sem5 to use libsupport

* nptl/tst-sem5.c: Remove unused headers. Add <support/check.h>. (do_test)
  Use libsupport test macros rather than hand-coded conditionals and error
  messages. Ensure that sem_init returns zero rather than not -1. Use
  <support/test-driver.c> rather than test-skeleton.c.
