    Cygwin: Use parallel make on AppVeyor
    
    We're bumping up against the 1hr free job duration limit on AppVeyor, so
    use 'make -j$(nproc)' to allow things to build slightly faster.
    
    Restructure the way build_script: is written in YAML, so it's slightly less
    repetitive and easier to add that.
    
    Also skip 'make check' on x86, since it currently just hangs. :(
