Hi,

When running gdb.mi/mi-sym-info.exp on openSUSE Leap 15.1, I get:
...
FAIL: gdb.mi/mi-sym-info.exp: List all functions matching type void \
  (unexpected output)
FAIL: gdb.mi/mi-sym-info.exp: -symbol-info-variables --max-results 3 \
  (unexpected output)
FAIL: gdb.mi/mi-sym-info.exp: -symbol-info-types --max-results 4 \
  (unexpected output)
...

The executable contains debug info from files other than the source files:
...
$ readelf -wi mi-sym-info | grep "DW_AT_name.*\.[cS]$" | awk '{print $8}'
../sysdeps/x86_64/start.S
init.c
../sysdeps/x86_64/crti.S
src/gdb/testsuite/gdb.mi/mi-sym-info-1.c
src/gdb/testsuite/gdb.mi/mi-sym-info-2.c
elf-init.c
../sysdeps/x86_64/crtn.S
...

The test does not expect this extra info, resulting in matching failures.

Fix this by restricting the failing commands using --name.

Tested on x86_64-linux.

OK for trunk?

Thanks,
- Tom
