fix for configure.in

[Dave Love]

I understand there's going to be a bug-fix version of 21.3.  This
fixes the check for libjpeg under Irix with the proprietary cc, for
instance.  Sorry I didn't spot it before, and I guess Irix isn't
getting other useful testing.

(The CVS head code is OK since I re-wrote that bit for autoconf 2.5x.)
