    gdb: testsuite: print explicit test result for gdb.base/dfp-test.exp
    
    In the current code, if decimal floating point is not supported for
    this target, there is no binary file dfp-test, and also there is no
    test result after execute the following commands:
    
      $ make check-gdb TESTS="gdb.base/dfp-test.exp"
      $ grep error gdb/testsuite/gdb.log
      /home/loongson/gdb.git/gdb/testsuite/gdb.base/dfp-test.c:39:1: error: decimal floating point not supported for this target
      [...]
      $ cat gdb/testsuite/gdb.sum
      [...]

                      === gdb Summary ===
      [...]
    
    With this patch:
    
      $ make check-gdb TESTS="gdb.base/dfp-test.exp"
      $ cat gdb/testsuite/gdb.sum
      [...]
