Interim build-snippet.

The AntLibs depend on the common build infrastructure supplied by the 
antlibs-common project. In subversion these are included via svn:external
directive. After migration to git there is need to have successor to that
directive. Until we have that, we could do a 'manual' git-clone.

The original of this snippet is maintained in the antlib-common project.
