kernel-toolchain won't compile

[Martin Galvan]

Hey, how's it going? I'm currently trying to cross-compile CURRENT for a
Cubieboard1. I'm following this tutorial:

https://wiki.freebsd.org/FreeBSD/arm/Cubieboard

However, when I try to compile the kernel toolchain I get the following
error:

===> lib/ncurses/form (cleandir)
Unknown modifier 't'

Error expanding embedded variable.
*** Error code 2

Stop in /home/ppsmartin/FreeBSD-CURRENT/lib/ncurses.
*** Error code 1

Stop in /home/ppsmartin/FreeBSD-CURRENT/lib.
*** Error code 1

Stop in /home/ppsmartin/FreeBSD-CURRENT.
*** Error code 1

At first I thought it was because I used TARGET_ARCH=armv6, but it also
happens when doing make kernel-toolchain TARGET=i386. Anyone else is having
this issue?
