Build script about ksm_preload

[unbrice]

Hi, and thanks for your contribution!
It prompted me to actually simplify the build system using cmake and published a documentation, it should be mush easier now. Please check it out and tell me if that solves your initial problem or if you'd still prefer that I had a build.sh
Thanks again,
Brice

From some vague memory of some earlier package I'd struggled with, I recalled the command autoreconf -is. That seems to work to replace the first 5 commands you have there, but I'm not entirely sure how autotools works so it may not be the same thing.

Build works fine here.
