Wasn't there a recent change to ld so that NEEDED entries are only
added if the shared library is needed to resolve symbols?

Which makes the naive addition of -lpthread useless.

I also dug into some linux libc.so and libpthread.so.
AFAICT the mutex and condvar functions are in libc.
There are somes stubs in libpthread that do a jump indirect,
not sure what that is based on though.
