I'd rather not - unless it actually has been submitted upstream and there
was some indication the change was tolerable to the GCC folks (or its
clear they aren't working with us on a solution).
I do think it needs to get into RELENG_7_0 ASAP, though. How about
committing it just to RELENG_7* for now?

If I may suggest the FSF-style formatting:
