    Add targets/pseudo/bootstrap-packages
    
    Try to compensate for the lack any origin for a DIRDEPS build.
    
    bootstrap-packages will extract the PACKAGE lines from
    the tree's Makefiles and use them to populate
    targets/packages/Makefile.depend and targets/packages/*/Makefile.depend
    so we can at least try to keep the Makefile.depend files throughout
    the tree up to date.
    
    This is far from ideal, as we cannot (easily) take into account
    options that affect the contents of various packages.
