    gdb/testsuite: update a pattern in gdb_file_cmd
    
    When building GDB with the following CFLAGS and CXXFLAGS as part of
    configure line:
    
        CFLAGS=-std=gnu11 CXXFLAGS=-std=gnu++11
    
    Then run the selftest.exp, I see:
    
    ======
    Running /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.gdb/selftest.exp
    ...
    FAIL: gdb.gdb/selftest.exp: run until breakpoint at captured_main
    WARNING: Couldn't test self
    
                    === gdb Summary ===
    
     # of unexpected failures        1
    /home/lee/dev/binutils-gdb/gdb/gdb version  13.0.50.20221206-git -nw -nx
    -iex "set height 0" -iex "set width 0" -data-directory
    /home/lee/dev/binutils-gdb/gdb/testsuite/../data-directory
    ======
    
    It is the fact that when I use the previously mentioned CFLAGS and
    CXXFLAGS as part of the configuration line, the default value (-O2 -g)
    is overridden, then GDB has no debug information.  When there's no debug
    information, GDB should not run the testcase in selftest.exp.
    
    The root cause of this FAIL is that the $gdb_file_cmd_debug_info didn't
    get the right value ("nodebug") during the gdb_file_cmd procedure.
    
    That's because in this commit,
    
      commit 3453e7e409f44a79ac6695589836edb8a49bfb08

        Clean up "Reading symbols" output
    
    It changed "no debugging..." to "No debugging..." which causes the above
    problem.  This patch only updates the corresponding pattern to fix this
    issue.
    
    With this patch applied, I see:
    
    ======
    Running /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.gdb/selftest.exp

    /home/lee/dev/binutils-gdb/gdb/testsuite/../data-directory
    ======
    
    Tested on x86_64-linux.
