I received the same error for the last couple weeks.  It happened
with freshly checked out sources, no /usr/obj and an empty
make.conf.

Going through the make.conf options I used when installing my last
world, I suspected NO_TOOLCHAIN may be the problem.  I checked out
sources from the date I built my last world and kernel, undefined
NO_TOOLCHAIN, and built/installed a world from that date.

I no longer get this error when building current sources.  If
you have an old toolchain installed, update that first.
