    ports/unix/check: Split depfiles for faster build
    
    Having just one depfile (.depend) means it has to be fully regenerated
    on every change, and it can't be done in parallel.
    
    After this change the rebuild time after touching a single test file has
    gone from 5.0 to 0.9 seconds. (make -j12)
    
    Build of tests from clean has gone from 8.1 to 5.5s.
    
    We could go even further and have one depfile per c-file, but this felt
    like a simple first step giving a nice improvement.
