Nothing prevents people from doing this, but in that case they have to
use the "Custom tarball" option and give the full URL.

The "Custom version" only works with versions that are available
directly in http://www.kernel.org/pub/linux/kernel/v2.6/.

I have separate build and install steps. Would something like the
following be OK for you ?

 * build step
	make <format>
	if modules:
		make modules

 * install step
	cp .... $(BINARIES_DIR)
	if modules:
		make modules_install
