Oh lol, sorry I didn't realise install was in the arch Makefile.

Hmm weird. I did bisect it:
# bad: [d79424137a7312d381d131d707a462440c0e8df9] kbuild: do not update config when running install targets
git bisect bad d79424137a7312d381d131d707a462440c0e8df9
# good: [9c2af1c7377a8a6ef86e5cabf80978f3dbbb25c0] kbuild: add .DELETE_ON_ERROR special target
git bisect good 9c2af1c7377a8a6ef86e5cabf80978f3dbbb25c0
# first bad commit: [d79424137a7312d381d131d707a462440c0e8df9] kbuild: do not update config when running install targets
But you're right. I must have messed something up while bisecting.
Sorry for the noise.
cheers
