Cross compilation is virtually always with
GCC, and frequently to a relatively sane (if limited) target.

So, for cross compiling, relaxing tests that are AC_TRY_RUN()
for some oddball legacy Unix system to an AC_LINK_IF_ELSE()
is generally going to be fine.

Anyways, I spent a ton of work on cross-compiling prior to
2.2.0, so if you haven't tried cross-compiling since then,
I'd advise trying it and/or reading the source code.
