configure.ac: add -pthread to PTHREAD_LIBS
As described inline - follow what's written in the manual and what works for all platforms that Mesa supports. We want to untangle things leaving only -pthread, yet that has a potential of causing regressions. Thus we'll do it as a follow-up patch. As a nice side-effect this resolves issues, where the system lacks libpthread.so, yet the linker does not warn about it and we and up with unresolved symbols.
