Ok, thanks for the explanation. However, I'm wondering if we want to
support this. By doing this, you completely circumvent the preparation
work that is done by Buildroot: when you do make tiff-rebuild, only the
building and installation steps are re-executed with a different
TARGET_DIR. So any preparation work done before, such as directories
created by the global "dirs" target (on which all packages depend) will
not be done in your new TARGET_DIR.

Peter, Fabio, any opinion on this?
