The problem to be solved is the long time it takes to do
"make modules_install" when working on a single module.
Instead of bringing in more or less complex solutions what about
extending "make dir/module.ko" to include the installation of the
module.

Something like:
"make MI=1 dir/module.ko"
where MI=1 tells us to install the said module.

I'm not particular found of the syntax - anyone with a better proposal?

Untested sample patch below.
