Looks mostly good, but:

I don't like this, that is too fragile. If automake is changed, we'll
forget to update this.
If all you are about are the 3 additional variables, can't you instead
put them into env vars and query them in the tcl code using getenv?
Or append them into AM_RUNTESTFLAGS ?

Perhaps add this only if offload_additional_options is non-empty?
