  I don't think that's possible. You have no other option than to make a 
bunch of bool options, and convert them to strings in the .mk file.

	bool "af"

	bool "ak"


  Obviously you could write a script to generate all this. But I doubt we 
want to have it in the first place. In particular for locales, the 
BR2_ENABLE_LOCALE_WHITELIST fits our needs. And having a list of locales 
as a string isn't too user-unfriendly.

  If this is for the iso-codes package: the locales stuff is already 
covered by the generic options. I don't know what Thomas was going on 
about, because most of the 14MB gets removed again in the finalize step...

  The only thing that perhaps could be made optional is the installation 
of the xml files.
