This is the same version we have in-tree, so we can now outsource that
version. AFAICT, it works just as well as the version included in the "haiku"
package.
I've left the static libs in the main package as that seems to be the
convention among Linux distros.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
