I suppose. I prefer configure to just fail in that case, myself.
I don't want a random, and perhaps incorrect for my platform, default.

Sorry, I got confused. (And I think that kept you from reading my
suggestion properly.) Here it is, corrected:
3. AC_TRY_RUN lets the user specify how to run code on the target,
e.g. with a --with-try-run=foo.sh option, where foo.sh is
a script that runs the given command remotely, e.g. via ssh.
(By default, configure would assume you can't run code on the target
when cross-compiling, just like now.)
Does that make more sense?
