Add step to find-debuginfo.sh script to compress annobin notes.
    
    With the introduction of the annobin gcc plugin to the build process,
    built binary files have become larger.  Sometimes significantly so.
    This is a patch that adds a new step to the post-link process performed
    by rpmbuild, to run the objcopy program with the --merge-notes option
    specified.  This will reduce the size of the annobin notes in binary
    files, thus alleviating the size growth.
