Fix dejagnu test support for --tool_opts
Right now it concatenates it with the existing options and then appends
it to that list, fix it to simply append it as is, same as it is done

Tested by running the following command which includes gcc options:
$ make check RUNTESTFLAGS="--tool_opts '-Werror'"

Inspecting the logs shows that -Werror was indeed used when compiling
