[PATCH] gdb: Remove duplicate "gdb Summary" in the test output

[Tiezhu Yang]

There exists duplicate "gdb Summary" in the test output, just modify
gdb/testsuite/Makefile.in to remove the redundant info.

Here is an example, when execute the following command:

  make check-gdb TESTS="gdb.base/a2-run.exp"

we can see the following info in the output:

  Running /home/loongson/gdb.git/gdb/testsuite/gdb.base/a2-run.exp ...

          === gdb Summary ===

  # of expected passes        9
  /home/loongson/build.git/gdb/gdb version  13.0.50.20220625-git ...

          === gdb Summary ===

  # of expected passes        9
  /home/loongson/build.git/gdb/gdb version  13.0.50.20220625-git ...
