Interesting. I've built posix threaded libraries on systems with and
without nptl and not had any problems moving the binaries from one system
to another. I thought glibc would be smart enough to figure out what you
have and use that, but I guess not. Perhaps I have just gotten lucky by
not using any problematic features or something.
