I don't think we should set host_arch here it should have been supplied by the
consumer of v8.gyp. When used in Chromium this should all be set up.

I also think -fPIC should be provided by the consumer of v8.gyp. We don't set
-fPIC for any other targets in this file.

Done.

Does the preparser actually care about the v8_target_arch?

Also I think that the only case where v8_target_arch != target_arch makes sense
is when v8_target_arch is arm and target_arch is ia32 (independent of
host_arch).
