This rips out the dwz support by default to make Roland happy, or at least a little bit less cranky :) Unless one uses --enable-dwz no dwz multi-file support code is included. The DW_FORM_GNU_ref_alt/strp_alts are still recognized, but any usage in libdw will just produce an error because no alt files are ever looked up or opened.
Committed and pushed.
