Specifically:
1) In webkit.gyp and test_shell.gyp, convert the rules to actions because of different grd outputs (localized grd files have locale in the .pak filename).
2) In chrome, make two targets each with a custom rule.  One target is for localized resources, the other for non-localized resources.  This is like the current windows build.
