NO_TOOLCHAIN broken in -current ?

Hello,

is the NO_TOOLCHAIN option broken in -current ?

without NO_TOOLCHAIN in make.conf buildworld runs just
fine, with it it fails as below:

-current cvsupped today. 
-removed /usr/obj/
-time synced.

Below the relevant error messages and my make.conf:

make.conf:
CFLAGS= -O -pipe
COPTFLAGS= -O -pipe
KERNCONF= KWETAL
NO_TOOLCHAIN=YES

I ran into this when building a nanobsd image.
Same error message. Building nanobsd image runs
after removing NO_TOOLCHAIN.

Any ideas ?
