* Added support for "thin" archives which contain pathnames pointing to
object files rather than the files themselves and which contain a
flattened symbol index for all objects, and archives, which have been
added to the archive.
* Added -F switch to objdump to include file offsets in the disassembly.
* Added -c switch to readelf to allow string dumps of archive symbol index.
