TESTED WITH:
    Qt-dev (from git)
    Python-3.5.2
    sip-4.19.1
    PyQt-5.8

NOTES:
    - installs pyqtdeploy to dev SYSROOT, symlink to ~/bin
    - other 'python' exes are used from respective SYSROOT

TODO:
    - change $SYSROOT/src to $SYSROOT/build b/c that's where pyqtdeploy expects it to be
