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.
