But it's not failing in that way in the emacs-24 branch on hydra, which
also uses pkg-config 0.23. So the problem is in pkg.m4 that older
pkg-config supply, not the pkg-config program.
I think it's that they don't do the equivalent of
--exists && --cflags && --libs

I think this is equivalent to my suggestion of copying pkg.m4 from a
recent pkg-config into our m4 directory.
But assuming we can get a newer pkg-config on hydra, I think it would be
fine to require >= 0.26 in autogen.sh, and leave configure.ac alone.
