Yes.  libpthread uses extern inlines without providing a default
implementation in the library.  Depending on which gcc you use, it can
trigger these bugs.

Neal, do you want to look at it?  I tried, but these cases seem a bit
confusing.  _pthread_self can just be attributed always_inline, but
for __pthread_spin_lock I am not sure.  The comments in the generic
code don't match the code in the L4 port.
