From: Jan Blunck <jblunck@suse.de>
Subject: Let debuginfo packages provide the build-id

This patch lets debuginfo packages provide build-id like follows:

 debuginfo(build-id) = c63cb23876c5fa85f36beaff58f8557e1bf22517

Users can therefore ask zypper to install the correct debuginfo package with:

 zypper install -C "debuginfo(build-id) = c63cb23876c5fa85f36beaff58f8557e1bf22517"
