latest VM images fail to compile for ARM

[Dan Raymond]

The latest two VM images here:

ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/VM-IMAGES/11.0-CURRENT/amd64/

are:

FreeBSD-11.0-CURRENT-amd64-20141025-r273635.vmdk.xz
FreeBSD-11.0-CURRENT-amd64-20141113-r274463.vmdk.xz

They won't compile ARM images using crochet.  I am getting errors while 
building xdev.  This looks like a regression because I have no problems 
with the previous VM image 
(FreeBSD-11.0-CURRENT-amd64-20140918-r271779.vmdk.xz).
