[COMMITTED] NPTL: Add stubs for Linux-only extension functions.
Commit Message
These four are nonstandard functions for which the only implementations
are pure Linuxism. I've added ENOSYS stubs that are OS-generic. The
getname/setname interface could be implemented "generically" to just
store and fetch the name locally, but that is probably not of much use.
Thanks,
Roland
