Pull extable.h fix from Paul Gortmaker:
"Fixup for arch/score after extable.h introduction.

It seems that Guenter is the only one on the planet doing builds for
arch/score -- we don't have compile coverage for it in linux-next or
in the kbuild-bot either. Guenter couldn't even recall where he got
his toolchain, but was kind enough to share it with me so I could
validate this change and also add arch/score to my build coverage.

I sat on this a bit in case there was any other fallout in other arch
dirs, but since this still seems to be the only one, I might as well
send it on its way"
