Patch: FYI: configure cleanup and reduction

[Tom Tromey]

I'm checking this in.

Inspired by Dalibor, I looked at our calls to AC_CHECK_FUNCS and
AC_CHECK_HEADERS.  It turns out we were calling them multiple times
when there was no reason to.  This consolidates the calls and
beautifies a little.  The resulting 'configure' is 20K smaller.
