Can't build world for ARM on FreeBSD-9.0-CURRENT

[Mattia Rossi]

When trying to cross-compile world with TARGET=ARM on a box running 
CURRENT, it fails with the following error (short version):

--------------------------------------------------------------

Tried on two boxes, one running i386, one running amd64. Fails on both.

Works on 8.2 though. It's a bit annoying.

Any hints?
