	help
	  Whitespace seperated list of locales to allow on target.
	  Locales not listed here will be removed from the target.
	  See 'locale -a' on your host for a list of locales available
	  on your build host, or have a look in /usr/share/locale in
	  the target file system for available locales.

	  Notice that listing a locale here doesn't guarantee that it
	  will be available on the target - That purely depends on the
	  support for that locale in the selected packages.

	  specified with or without encoding, when no encoding is
	  specified, UTF-8 is assumed. Examples of locales: en_US,
	  fr_FR.UTF-8.

# glibc and eglibc directly include gettext, so a separatly compiled
# gettext isn't needed and shouldn't be built to avoid conflicts. Some
# packages always need gettext, other packages only need gettext when

# should rely on the following two options.
