These are now fixed in Linus' tree by:

h>"")

Good.

Can you tell we don't test that combination very often :/
That's why you have a special config for it? ;-)

sh4/sh-randconfig (doesn't seem to be a new issue, seen before on v4.12=
-rc3)
I think I'll disable that one, it's been broken more often that not and
I doubt anyone is that motivated to fix sh4 randconfig breakages?
Probably not. Usually I ignore the commonly seen issues.
This one was more uncommon, so I kept it.
Relatedly I might move all the randconfig targets from Linus' tree into
a separate "linus-rand" tree, so that they don't pollute the results, as
I've done for linux-next.
Sounds look a good thing.
