I've applied these changes to update the ARM and MIPS ports for the move
of NPTL to use hidden_def instead of _internal function aliases.
Other architectures (alpha, ia64, hppa, m68k, tile) will need similar
changes. hppa does more complicated things with _internal function names
and I don't know exactly what will be right there.

Yes, for hppa the Linuxthreads->NPTL transition was more difficult,
and required a wrapper around pthread_cond* functions to manage the
state of a possibly statically initialized pthread_cond*.
We call the _internal functions from the wrappers after initializing
pthread_cond* variables.
Is that still possible?
Cheers,
Carlos.

Yes, that's still possible. What we're eliminating is use of _internal
aliases for the same purpose as things such as hidden_def (INTDEF / INTUSE
elimination, bug 14132); if the _internal name is actually wrapped rather
than being another name for the same function, that's fine.

Done for alpha. Obvious patch elided.
