It looks very sane to me.  This is probably how the AVR and CR16 should
have been handled to begin with IMHO.

FWIW, I generally discourage ports overriding default options, but this
is a case where I believe it makes some sense.

Please move forward with an official submission.


I've now bootstrapped and regression-tested the previously posted patch
on x86_64-linux-gnu, as well as retesting it on nios2-elf after updating
my source tree to current mainline head.

Are the target-independent parts OK to commit?

Yes.  Please install.

Thanks,
Jeff
