My upcoming changes to use our "futexes" instead of semaphores
will obviously not work on non-Haiku platforms, so we now
need a copy of this class in libbe_build.
* libbe_build: Where possible we directly use the actual Haiku headers and
sources, now. In the headers/build headers we just include the respective
Haiku headers as needed. That still allows overrides where necessary. The
intention is to make it easier to keep the build stuff in sync.
* Fixed a few printf() format and signed/unsigned comparison warnings.
