toolchain: rework thread options
The selection of linuxthreads, linuxthreads old or NPTL doesn't make a
lot of sense for external toolchains. So, instead, we :
* Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be
selected by toolchain specific options when thread support is
available. Package needing to test thread support should use this
option.
* Move the none/linuxthreads/linuxthreads old/NPTL selection to
Buildroot internal toolchain configuration.
* Add an option in external toolchain to tell if thread support is
available or not in the external toolchain. We assume that glibc
without threads is not possible, as Ulrich Drepper said in
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html
ffmpeg, dmalloc and openvpn are fixed to use the new
BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix
is no longer used, as the configure script doesn't even understand
this option.
