Why weak referencing pthread_equal() in k5-thread.h?

I'm looking into this, and can't reproduce the problem.  I'm working 
with NetBSD 2.0 on an alpha, and looking at our "kinit" and "klist" 
binaries, which don't get linked against libpthread; what version are 
you using?

If you're using netbsd-current and they've added a stub for 
pthread_once to libc, I think that would explain the problem, and I'd 
need to know the name of a function in libpthread that they didn't add 
a stub for.  I could use pthread_equal, or pthread_join, or ....

And it occurs to me that this could be a compatibility problem with 
future versions of an OS, if they add a stub for the routine we're 
testing for.  Perhaps I should think about changing the code to test 
all of the functions we use, or at least all the ones we indicate are 
weak.
