After this commit I couldn't build gnucash anymore on linux. It turns out that 
pkgcheck adds a library dependency (-lltdl) that was not there in the guile 
configure code before.

It's not a big deal in itself, I quickly figured out I had to install
libtool-ltdl-devel on my Fedora system to get it to build again.

I'm just bringing it up because I think it would be good to mention this in 
the build dependencies. I'm just not sure what is the most up to date piece of 
documentation we have for that. There's a README.dependencies in the src 
directory, but that looks horribly out of date. So is there another place we 
document build dependencies ?

Other than that, I'm very happy with this change. It clearly simplifies and 
normalizes the configure code. Yay !
