    lang/swift510: fix build on low RAM, ccache support
    
    The port did not pass down MAKE_JOBS_NUMBER to swift's build
    scripts, and Swiwt/LLVM are C++ ports and memory hungry.
    
    Also, due to lack of CCACHE support, the port cannot pick up
    where the OOM killer struck easily in, say poudriere.
    
    Pass down --jobs ${MAKE_JOBS_NUMBER} if MAKE_JOBS_NUMBER is
    defined and not empty.
    
    While here, also support CCACHE builds so we can actually restart
    in case the MAKE_JOBS_NUMBER is still too high relative to the
    build host's memory.
    
    This let me successfully build in one single attempt
    with MAKE_JOBS_NUMBER=5 in /etc/make.conf on a 16 GB computer
    that previously failed persistently because the port
    attempted to build with all I have, meaning 16 jobs.
    
    While here, support CCACHE build.
