since apparently it wasn't tested when being merged

* Fixed the _devel package so that it actually contains devel stuff
  (in particular the static libs and shared lib symlinks)

* Enable ICU support

* Enable parallel building

There should probably be a _doc package and we might want to split the
_devel package with a separate package for each of the libs.
