To handle the situation I mentioned, the build system would need to either tell
the installkernel script what to do, or call different installkernel scripts,
so the build system itself needs to have some notion of what install means,
but as I mentioned, that is currently missing from the makefiles.

But I would like to...

I guess you misunderstood me.  I'm not objecting nor saying it shouldn't be
done, just stating some of what needs to be done to make it work properly.
The logic needed is not trivial, and more work is needed than just adding
an 'install' target line to a makefile.
