[RFC] Provide source files for useful debug packages
Debug packages are fairly useless currently because the soucre files
needed for stepping through code etc are not packaged with them. This
patch adds the needed source files to the debug package and adjusts
the debug info to look at the /usr/src/debug/ directory for them rather
than the build location. This requires using the "debugedit" program
which is provided as part of the RPM sources.
