Dimitry Andric 956168c802 Ensure correct pthread flags and libraries are used ... On most platforms, certain compiler and linker flags have to be passed when using pthreads, otherwise linking against libomp.so might fail with undefined references to several pthread functions. Use CMake's `find_package(Threads)` to determine these for standalone builds, or take them (and optionally modify them) from the top-level LLVM cmake files. Also, On FreeBSD, ensure that libomp.so is linked against libm.so, similar to NetBSD. Adjust test cases with hardcoded `-lpthread` flag to use the common build flags, which should now have the required pthread flags.
