Log Message:
tests/lib/libpthread: Test unloading libpthread after lazy binding.

If you dlopen libpthread and dlclose it again, the thread stubs like
pthread_mutex_lock need to continue working -- a library might have
calls to it in order to support thread-safety for threaded
applications, but that library needs to continue working even in
non-threaded applications after lazy binding of the libpthread symbol
instead of the libc stub.

PR lib/59784: dlopening and dlclosing libpthread is broken
