I suspect the easiest thing to do is for autoconf to detect which
to use and then to pass it to mkdep as an additional argument.

Of course, -x has special meaning on some compilers.

We could switch to something that used -E or cpp directly, but that
raises other portability issues.

I'll look about at other packages and see how they resolve this
issue.
