I guess you mean this is a followup for *other* languages, since chinese has been dealt with.

Bug 1089363 only solve zh-TW's problem.
This issue actually affects to other language. But not so obvious.

The root cause should be the OSX(since 10.10) change the rule for language of native dialog.
Before 10.10, it will use user's choose (system preference > language and region) 
But since 10.10 it follows application's language.

And the old makefile will use AB part of AB_CD locale define.
'zh_TW' are recognized as 'zh' in OSX.
And the default language of 'zh' in OSX is zh-CN (not sure how OSX decide it, alphabet order or config).

There are other similar cases.
ex: 'en_US', 'en_GB', 'pt_PT', 'pt_BR'

Maybe these locales are ok since there wording are all the same.
(locale also affect metrics, number/date format. not only language)
We still have to see how many locales are affected like 'zh-TW'.
And find a general solution for all locales if possible.

Yes, just writing more details.
I have to write a reproduce steps based on the create form.
So I take Chinese as sample.
