I'm putting this on both trunk and 2.22 branch. It is a user-visible
change and I didn't bother filing in bugzilla, because no NaCl application
developer will actually see the 2.22-release version before this change.
Thanks,
Roland

* sysdeps/nacl/Makefile [$(subdir) = misc] (sysdep_headers):
Use 'override' keyword to freeze the value here, preventing
the addition of sys/mtio.h by sysdeps/gnu/Makefile.
