docs breaking my make release

[John Baldwin]

I'm trying to build a release with docs for some more ISO layout tweaks, but 
the doc build keeps failing.  Any ideas?

make -d fl output seems to show it breaking here:

#
# Create /usr/obj image subdirs when ${IMAGES} contains subdir/image.xxx
#

_imagesubdir=
.for _imagedir in ${IMAGES:H}
.if ${_imagesubdir:M${_imagedir}} == ""
_imagesubdir+= ${_imagedir}
.endif
.endfor

(debug output below)

Any ideas?
