Commit: Fix compiling resbin.c with clang 14

[Nick Clifton <nickc@redhat.com>]

Hi Guys,

  I recently upgraded my machine to Fedora 36, and this brought in a new
  version of Clang (version 14), which promptly started issuing a new
  warning message when compiling the binutils: 

     binutils/resbin.c:1219:76: error: parameter 'length' set but not used [-Werror,-Wunused-but-set-parameter]

  So I am checking in the patch below to fix the problem.

Cheers
  Nick
