Argh, yeah, you're right -- my custom scripting was confusing the issue,
by rerunning configure automatically with the options previously in the
cache file. I had the equivalent of "configure ; make" so when
configure failed, the make step re-ran configure using the options in
the cache file, which did not have --with-lz4.
