Remove gdb-lineno-makeup-test.patch
    
    An equivalent test has been merged upstream in this commit:
    
      commit ef56b006501ba52b128d4e5f36657ddbf56d22bc
      Date:   Wed May 17 15:14:15 2023 +0100
    
          gdb/testsuite: test for a function with no line table
    
    As this is only a test there seems little point in backporting this
    commit to Fedora -- we'll pick it up next time we rebase.  For now I
    suggest that we drop this patch.
