libpthread failures in macppc

[Julio Merino <jmmv%NetBSD.org@localhost>]

Hello,

With a recent build of NetBSD/macppc, I'm getting several segfaults and
stuck programs that seem to point at libpthread issues.  All their
backtraces point at some pthread function.  (I had not touched this
machine for a while, so I don't know when this started happening.)

Running the tests in lib/libpthread under my macppc machine (a Mac Mini
G4) gives these failures:

===> Expected failures

The stacktraces look like this:

Any ideas?
