* readelf.c (process_program_headers): Add comment about return
value. Ensure that 0 is returned if the headers are not loaded.
(process_file): If process_section_headers failed to load the
headers disable any tests that rely upon them. Similarly for
process_program_headers.

* po/da.po: Updated Danish translation.
