Subject: [PATCH] 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.
