Either in your package .mk file or in a local.mk file, you can add:

FOO_OVERRIDE_SRCDIR = /path/to/foo/sources/

If you do that, then Buildroot will no longer download/extract/patch
the sources for the foo package, it will directly assume the sources
are located in /path/to/foo/sources/. It will rsync them to the build
directory, and build from there. Whenever you do:

	make foo-reconfigure

or

	make foo-rebuild

Buildroot will rsync again the source code, and restart the build at
the configuration step, or the build step of the foo package.

Usually, /path/to/foo/sources/ will be the directory where you did your
Subversion checkout or Git clone of your "foo" source code.

Best regards,

Thomas
