libthreads: Remove

libthreads is most probably completely broken, and not the long-term
road anyway.

* config.make.in (VERSIONING): Remove.
* configure.ac: Test for pfinet assembly compatibility instead of
libthreads assembly compatibility. Do not set VERSIONING.
* libthreads: Remove directory.
* Makefile (lib-subdirs): Remove libthreads.
* doc/hurd.texi (Threads Library): Rename references to libthreads into
libpthread.
* release/rfloppy.copy: Do not objcopy lib/libthreads.so.
* release/tool-Makefile (rfloppy-solib): Remove libthreads.
