Humm, I probably should have explained better how GitlabCI works.
It works creating a docker container that have a limited lifespan of 3h max.
After that the time is over, this container ceases to exist, leaving no build
objects, only the console log. So there is no way of 'resuming' the building
from where it stopped. I used the 'job' term because it's how they call it,
and I understand it's easily confused with bash jobs.

I understand your viewpoint.
But what I propose is not to change that assumption, but instead give some
Makefiles the aditional ability to be called directly and still not build stuff
if they were not enabled in .config.

But, why these chosen Makefiles, and not all of them?
Granularity.
What I am trying to achieve with this patchset is the ability of building
smaller sets of drivers without accidentally building what is not enabled
on .config.
And, in my viewpoint, building a single drivers/DRIVERNAME is small enough to
be fast in most situations.

This change is not supposed to bother the usual way of building the kernel, and
it is not even supposed to add overhead to kernel compilation. And it would,
at least, solve my problem with the 3h limit, and enable the tool
I am building on GiltabCI to help other developers.

Thanks for reading,

Leonardo Bras
