Consolidate libraries list in project file a bit.

Instead of having to mention each library several times (extra targets, target
dependencies, linker flags) create a list of libraries we build directly and
create all other lists from them. Note that libraries get processed in the
order of the list, which is important for linking order. As a result libucl
needs to come last.
