commit 0f162dc41f2051eab237bd223356d88e94a07580
Author: Mark Wielaard <mark@klomp.org>
Date: Mon Jun 26 17:38:30 2017 +0200
find-debuginfo.sh: Don't create dwz multi file if there is only one .debug.
dwz -m multi only works when there are multiple .debug input files.
With just one .debug file it doesn't really make sense to extract
the shared debug info into a separate file and dwz will complain:
dwz: Too few files for multifile optimization.
So only add -m multi if there is more than one .debug file.
