Commit: Add linker diagnostic message about missing static libraries

[Nick Clifton]

Hi Guys,

  I am applying the patch below in response to a user request for a more
  helpful error message from the linker if it fails to find a static
  library.  (The request is RHEL-69758 for those with access to the RHEL
  jira system).

Cheers
  Nick
