DWP files don't usually have a GNU build ID built into them. When searching for a .dwp file, don't require a UUID to be in the .dwp file. The debug info search information was checking for a UUID in the .dwp file when debug info search paths were being used. This is now fixed by not specifying the UUID in the ModuleSpec being used for the .dwp file search.
