Err none of the above. The RedHat binutils doesnt have a 'package'
string.  With brackets.  For example,

   GNU assembler (GNU Binutils for Ubuntu) 2.24
                                           ^^^^
   GNU assembler (crosstool-NG 1.20.0 - nbsps) 2.24
                                               ^^^^
It is just, 

   GNU assembler version 2.24.0-6.fc21 20140613
   -----------------------------------
                         ++++++

Below gets the first ##.## after a bracket or the first ##.## No
escaping of the . is needed inside the range of course.
