check_packages : add support for split packages.

I just found a way to support split packages, by using $(type
package_${pkg}), parsing that output and running eval on the relevant lines.

This is a bit ugly, and while it works fine on my machine and my current abs
tree, I cannot guarantee this code is bug free :)
