The linker has a -plugin-opt option. You probably do something like

-fplugin-opt=-mcpu=

On the gcc plugin we just reexec gcc, so the plugin options are gcc
options. Not sure if there is much to be gained here since the two
plugins are independent.

You are free to name it, but using something similar to a llc option
is probably a good idea.
