Details:

The main reason people will build autoconf with --program-prefix or
--program-suffix is most likely that they want to support multiple versions of
autoconf at the same time.

For example, binutils requires 2.69 exactly, but if 2.70 is released then
people will want to use that before binutils has switched and released.

Using --program-suffix=2.69 means that the binaries are installed as
/usr/bin/autoconf2.69, but pkgdatadir is still just /usr/share/autoconf. 
Everyone who wants parallel installable autoconf then has to fix this somehow
(either overwriting pkgdatadir, or fixing the paths after installation).

I suggest overwriting pkgdatadir to respect $program_prefix and
$program_suffix.
