Downgrading from broken 9-stable src/ to 9.3-RELEASE solved everything!
Broken code in bsd.sys.mk relate to 11-current's use of clang V. gcc in 9.
There's other broken in 9-stable too
It is easy to check without rebooting, just
mount -t devfs dev /9stable/dev ; chroot /9stable ; cd /usr/src ; make
I've tested this on my current box, re-making a 9.3-RELEASE
I hope commiters try it, & back out broken 9stable commits.
Thanks
Cheers,
Julian
