[crosutils] Add script to help build incrementally

Browse Source 
cros_workon_make provides a make-style interface to incrementally building
    cros_workon-enabled packages, appropriately setting up the toolchain for
    the target board beforehand.

    To incrementally build your package:
      cros_workon_make --board <board> <package>

    To re-run your package's configure steps and compile:
      cros_workon_make --board <board> <package> --reconf

    To incrementally build your package and tests, and run the tests:
      cros_workon_make --board <board> <package> --tests

    To incrementally build and install your package:
      cros_workon_make --board <board> <package> --install

    To remove ALL files in your package repo not known by git:
      cros_workon_make --board <board> <package> --scrub

    With the exception of --scrub, these flags all compose
