Hello,

I also have a patch (below) that implements a similar feature
(<pkg>-rebuild and <pkg>-reconfigure), but it also does the "make"
again automatically as well to regenerate the root filesystem. The
implementation is a bit different, as it doesn't use a new fake stamp
file, but simply uses phony targets.

    package: add <pkg>-rebuild and <pkg>-reconfigure
    
    We are often asked "how can I restart the build of a package ?" or
    "how can I restart the build of package from the configure part
    ?". Obviously, tweaking with stamp files is possible, but not very
    user friendly.
    
    Therefore this patch adds two new per-package targets: <pkg>-rebuild
    and <pkg>-reconfigure. They will remove the right stamp files and
    restart the complete build process (by using the 'all' target, so that
    not only the package is reconfigured, recompiled and reinstalled, but
    the root filesystem images are also regenerated).
