Having done more experimentation with this, I've now got a better idea as
to why some things are the way they are. At this point I'm able to
successfully build kernels with this modification, but I doubt I'm even
close to full coverage. Yet the general approach does appear to work.
There are several places I'm rather unsure of. I've never used many of
the scripts and tools. As such I've got no idea whether they need
further adaptation. There is a good chance I may have broken some of
them.
I've ended up with the suspicion 16671c1e1cac2 was wrong. It may have
made some sense in 2015, but I'm now skeptical of it being a good
approach. In particular setting $(srctree) at the top of Makefiles in
tools/ looks like a workaround for 16671c1e1cac2. Perhaps this is part
of a superior solution to the referenced problem?
Much of scripts/ seems meant to be invoked by Makefiles. Yet some
portions may also be intended for use at regular shell command-lines.
Being unsure which category these fall into means further adjustment is
likely needed.
Again, right now I'm pretty sure my test coverage is quite incomplete.
Things Work For Me(tm), but we know how that goes. I've done some work
on avoiding broken intermediate states, yet my ego is smaller than
Jupiter so I'm less than optimistic I've gotten everything.
