RHEL3 is just about dead as far as Red Hat is concerned: only critical
security bugs will be addressed, and even that is going to stop in a
year or two. RH would certainly not recommend that you be trying to
put any new applications on that platform.

There isn't any reliable way to do that at configure time, I think.
We could add an AC_TRY_RUN call but it wouldn't be trustworthy; think
cross-compiles, or running on some other kernel version than where you
compiled. Unless the problem manifests on some not-quite-so-dead
platform, I'm not in favor of it.
