Please reflect this in the CL description. With this you're also migrating PPC
and s390 bots from gyp to gn.

Maybe rather make this two CLs and land the gyp-gn switch separately?

Note, we also run an automated comparison, please review it for anything that
sticks out:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20ppc%20...

Many flag changes are by design, but maybe there's something else PPC/s390
related that's missing? In particular the defines and other cflags of the
v8_base target.
