This is fragile and I worry that it's going to be easy for us to break. You need
to find a better way for this.

This is true, and the TODO is because of this. But since, this is a bring-up CL,
even with this piece being fragile, it might still be worth to give it a try on
the short term, and fix it in a follow up.

in patchset 12 , I replaced use_ozone by enable_package_mash_services, which
actually makes more sense to me, since it fixes chrome (x11/linux) --mash too.

wdyt?

I'm still confused by this. What are you trying to compile that is needing ash
resources? You should either be defining use_ash, or don't compile the ash files
that are attempting to pull in ash resources.
