libpthread: disable unimplemented configurations
When NPTL is available for an architecture just allow the use of it. If NPTL is not available for an architecture, allow to choose between LT and LT.old. This minimizes misconfiguration of threading library.

If you want to compile uClibc with NPTL support, then answer Y.
- IMPORTANT NOTE! NPTL requires a Linux 2.6 kernel, binutils
- at least version 2.16 and GCC with at least version 4.1.0. NPTL
- will not work with older versions of any above sources. If you
- ignore any of these guidelines, you do so at your own risk. Do
- not ask for help on any of the development mailing lists.

- !!!! WARNING !!!! BIG FAT WARNING !!!! REALLY BIG FAT WARNING !!!!

- This is experimental code and at times it may not even build and
- even if it does it might decide to do random damage. This code is
- potentially hazardous to your health and sanity. It will remain
- that way until further notice at which point this notice will
- disappear. Thank you for your support and for not smoking.
