compiler: stop iterator on error
If there is an error reading or parsing an archive header, the Archive_iterator code would return a dummy header but would not mark itself as done. The effect is that an invalid archive leads to an endless loop reading and re-reading the same archive header. Avoid that by setting the offset to the end of the file, which will cause the iterator to == archive_end. No test since it doesn't seem worth constructing an invalid archive.
