On a system without SDT probes in libstdc++, we run into:
...
FAIL: gdb.mi/mi-catch-cpp-exceptions.exp: all with invalid regexp: run until \
breakpoint in main (unknown output after running)
...
The test-case uses a regexp argument for the catch throw/rethrow/catch
command, which is only supported on systems with SDT probes in libstdc++.
Fix this by marking the portions of the test-case that use a regexp argument
as unsupported on a system without SDT probes.
Tested on x86_64-linux.
