I've actually added it to my tester just to see if there's any fallout.
It'll take a week to churn through the long running targets that
bootstrap in QEMU, but the crosses should have data Monday.
The first round naturally didn't trigger anything because the option is
off by default. So I twiddled it to be on at -O1 and above.

avr, c6x,
lm32-elf failed to build libgcc with an ICE in leaf_function_p, I
haven't isolated that yet.
There were other failures as well. But you've got a few to start with
and we can retest pretty easily as the patch evolves.
