Can't cross-compile HEAD

Hello

I'm trying to cross-compile HEAD r356551 for mips on my FreeBSD-12.1 amd64.
I'm using mips-gcc6-6.5.0 and this
https://github.com/freebsd/freebsd-wifi-build nice project to build
image for my tl-wdr3600

The error I'm getting is:
...

===> usr.bin/vi (all)
===> usr.sbin/freebsd-update (all)
===> usr.sbin/gpioctl (all)

Could anybody please help fix that?
