The problem is that we now always create the DOCSTRINGS files in the 
build tree.  So if you are doing a VPATH build from a tarball 
distribution, new copies will always be created in the build tree even 
though the files exist and are up to date in the source tree.  So then 
the DOCSTRINGS files have timestamps that are newer than the doc-cache 
file and we end up trying to recreate the doc-cache.  That can work for 
a normal build, but for cross builds it fails.  Rather than trying to 
play tricks with timestamps or write more files in the source tree, I'm 
switching to using Perl instead of Octave to build the doc-cache file. 
I have a patch almost ready to push.
