A-ha!, that was the problem.  One of these packages:

apt-get install gperf bison ruby flex

Must have been missing.  I use flex and bison, so expect these were already 
installed.
Probably ruby was missing.  *shrug*

It's now all cross-compiled properly.

Just for the record:  installing the Qt libraries in my previous posts was a 
Big Mistakey.
