The latest Autoconf can calculate the sizes of C objects even when
cross-compiling.  It does so without using AC_TRY_RUN.  So this much
at least should work without any special help.

Now, now, it's OK to use AC_TRY_RUN if there's a reasonable fallback
when not cross-compiling.  (Please don't stick pins into my doll's
head!  :-)

I seem to recall somewhat submitting a patch recently along those lines.
