One minor point:

Index: binutils/NEWS
===================================================================

+* Add --extract-symbol to objcopy.

It would be nice if you extended this description a little bit. We use the NEWS files to make the release notes for any given particular binutils release and just naming a new command line option without describing what it does means that it is unlikely to grab the reader's attention. Maybe something like:


  * Add --extract-symbol command line option to objcopy, which will
    strip everything out of an ordinary object file or executable except
    for its symbol table.  Files containing just symbols can be useful
    to some OSes.

Cheers
  Nick
