In some corner cases of static linking and unexpected libraries order on the linker command line, libc symbol might preempt the same libthr symbol, in which case libthr jump table points back to libc causing either infinite recursion or loop. Handle all of such symbols by using private libthr names for them, ensuring that the right pointers are installed into the table.

This configuration is only supported to make it easier to create e.g. loadable modules which must work correctly when dlope= ned either in threaded or in non-threaded process. That said, if we start distinguishing the value 0, we get the next problem = with pthread_getthreadid_np(3) which libc stub returns zero. We might fix this eventually, if the anticipated merge of libthr into libc occurs. sometime.

In some corner cases of static linking and unexpected libraries order on the linker command line, libc symbol might preempt the same libthr symbol, in which case libthr jump table points back to libc causing either infinite recursion or loop. Handle all of such symbols by using private libthr names for them, ensuring that the right pointers are installed into the table.
