It might be a good idea to remove the check for the word "version" here - 
"version" is not part of the GNU Coding Standards --version output so 
might go away.  Standard would be more like

GNU ld (GNU Binutils 2.17.50 20070220) 2.17.50

where the text after the last space is the real version number, and 
--with-pkgversion replaces the "GNU Binutils 2.17.50 20070220" with your 
name and version number for your binutils package.  I simply didn't fix 
all pre-existing problems with --version output when adding 
--with-pkgversion support.
