I withdraw this patch.  It doesn't fix anything...  I misread the 
testresults.  Sorry for the noise.

Instead, I propose skipping the test when running the testsuite against 
a stub.
Also, the mi2-file.exp test has the same problem.

Please find a new patch attached, review and commit.

Cheers,
Pedro Alves

      * gdb.mi/mi-file.exp: Skip test if use_gdb_stub is set.
      * gdb.mi/mi2-file.exp: Likewise.
