[rrd-developers] Small fix for autoconf

[Florian Forster]

Hi,

with my Debian Testing box I had to apply the following small changes to
the `configure.ac' file in order to make `autoconf' happy. Don't know
what the problem precisely is – m4 and its square parenthesis is too
high for me ;)

Also, autogen.sh specifies `-I config', but there is no config directory
in the SVN repository. That should probably be removed, too.

Regards,
-octo
