Hmm, I pulled this and then did an allmodconfig build.
I expected that to be a full rebuild, since the plugins got
recompiled, but it turned out to just take 16 seconds because it only
compiled the plugins, not any of the object files.
I'm doing a _proper_ full build with this after doing a
git clean -dqfx
to actually clean everything out, but it did make me go "Umm".
Maybe we don't care. I guess the plugins are all supposed to be stable
in the sense that any updates don't change the generated code. But it
does strike me as a honking big hole for verification of plugin
changes.
So I don't think this necessarily requires any changes to our Kbuild
infrastructure, but I thought I'd mention it since this clearly didn't
match my naive expectations.
