Cool.


We still get the result that arm[67], and possibly some mips,
have had a lot of -O2 use based on what has historically been
done by the qemu-user-static based official-build servers.

And that leads to questioning the need for -O instead of -O2
for armv[67] and possibly some mips contexts.

Or, going the other way: Should -O be forced and have an
exp run for, say armv7 ? An example of what would be found is
what I ran into for x11/pixman when its build used -O (native)
instead of -O2 (cross-build via qemu-user-static) and a link
command failed for -O use. (It was the failure that started my
looking for what was different from my prior cross-build that
had worked.)
