   7         Extensive changes to move the bulk of the linker into BFD so that
   8         more efficient backend code can be written for specific object
   9         files.  Only existing efficient backend is a.out.

 458         a SHT_NOBITS section to only do it for the last such consecutive
 459         section, and to really force page alignment.

 522         addralign of strtab sections to 1.
