This commit adds '--build-foo' options to force the script to build relevant libraries instead of trying to use packages from the distribution. In addition, it also now offers (with those '--build-foo' options) the possibility to build libraries on distributions that are not fully supported. This is limited, but should still help people once they have installed themselves the basics of dependencies - boost, llvm, osl/osd etc. are not libraries that are really easy to build. DISCLAIMER: I did not take the 20 (or more) hours needed to test all combinations over all distributions, and given the size of the changes, bad sneaky typos are quite probable, so please report if you get some errors!
