Configure fails because it checks explicitly for $prefix/lib/libpng.so

Configure fails because it checks explicitly for $prefix/lib/libpng. It's the same issue with libjpeg. This causes a failure on some systems (ie. Ubuntu Oneiric) because the library is not in /usr/lib but in /usr/lib/x86_64. I suppose we have to modify the explicit check to only the use of autoconf to check a lib.

@aboudreault can you test with this fix applied and report back ?

I've updated the scripts a bit so mapscript will also build. everything is in my bug-4315-autoconf-png-jpg branch, that you can try out with:

git remote add tbonfort git://github.com/tbonfort/mapserver.git
git fetch tbonfort
git checkout bug-4315-autoconf-png-jpg

Tested on a ubuntu precise and it works great. I've also seen that you fixed the libgd issue related to multi-arch. Using gd-config is a good thing too. Thanks!
