Not surprising, neither me/korg[1] nor kbuild nor linux-next have score
tc for build coverage, so score got the "this looks right" treatment.

Too bad your coverage didn't use linux-next over the last couple weeks,
as then it could have been in the pull request I'd just sent.  Oh well.

Mind if I ask where you got your toolchain?  I'm not in a position to
futz around trying to build one myself for some of these less common
architectures, but I'm not against extending my coverage using existing
toolchains.
