RDOFF patch from Yuri Zaporogets:

RDOFF patch from Yuri Zaporogets:

 - Panos Minos's LDRDF fix (correct export of relocation records);
 - Panos Minos's symtab.c verbose dump fix;
 - Librarian (rdflib) now puts a signature block when creating a library
   (instead of creating an empty file). In theory it doesn't break binary
   compatibility, but due to a bug in the original 'rdlib.c' you can't
   use old LDRDF with new libraries. Fix this bug as well.
 - Other minor changes in LDRDF.
