Subject: Add preliminary dependency handling support

Projects may now declare other projects it depends upon through
the file "dependencies" located in a project's $CONFIGS directory.
This file requires that each dependency listed, one per line,
correspond to a project in the $PROJECTS directory; the dependency
may be in any form accepted by the libreboot script, e.g:

./libreboot build $dependency

Multiple dependencies files, one per target, are read provided
they are located in target directories and those targets were
included in the list of arguments passed to the libreboot script.
