AFAICS this is the only test in our configure script that is a hard

We could just assume that /dev/urandom will be available --- that's no
worse than a lot of the other optimistic assumptions that configure
makes in that mode.
Agreed, I don't see a problem with that. I'm not terribly familiar with
supporting cross compilation in autoconf, would a reasonable approach be to
just remove the check altogether like the below sketch?
It seems like a useful test when *not* cross compiling, which is most
of the time.
You still don't know whether the file will exist on the system you are
running this on.
(I'm a bit surprised that the AC_CHECK_FILE macro doesn't provide
an action-if-cross-compiling option, but it apparently doesn't.)
Because you are only supposed to look for files that you need during the
build.
