I wonder if this would be better as just FULL_OPTIMIZATION_arm. That
said, the OPTIMIZATION variables are primarily distro knobs and it's not
entirely clear that individual packages ought to be overriding them at
all.

Does anybody know whether there is any actual science behind the use of
those flags on armv7a specifically?
