This is a first patch to let Wine run on either an NPTL enabled or not system.
The remaining issues deal with linking ntdll to libpthread, and autodetection in configure.
It's not production-ready yet, I'm aware that there are a couple rough edges (ie, nptl_check passing from libwine to ntdll, wine_pthread_init_(process,thread)_no_nptl, what really happens if run on a system without NPTL).
It's been tested on RH9 with NPTL.
