commit 3a7c5095401304d24ed4aa0d8f30c572097c7d33

    cmake: prefer CMAKE_BUILD_PARALLEL_LEVEL
    
    cmake 3.12 introduced this environment variable. Prefer it to passing
    PARALLEL_MAKE and PARALLEL_MAKEINST on the cmake command line, because
    it gets passed to second stage cmake invocations while command-line
    arguments do not (for example, multi-stage clang builds)
