Yeah, I'm imagining that we'll just detect it like we detect failures
to insert hardware breakpoints / watchpoints, at resume time.
Something like:

    set test "continue with catch syscall"
    gdb_test_multiple "continue" $test {
	-re "Could not insert syscall catchpoint.*$gdb_prompt $" {
              ...
	}
	-re "Breakpoint .*$gdb_prompt $" {
              ...
	}
    }

Thanks,
