	  then all locales supported by packages are installed.

config BR2_ENABLE_LOCALE_WHITELIST
	string "Locales to keep"
	default "C en_US de fr"
	depends on BR2_ENABLE_LOCALE_PURGE
	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.

# 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
# locale support is enabled. See the documentation for how packages
# should rely on the following two options.

	  functions, then everything will need to be compiled with soft
	  floating point support (-msoft-float).

	  If you are building your own toolchain then select the type of

	  Not all thread variants work with all versions of uClibc,
	  the "linuxthreads (stable/old)" may be a working fallback
	  if you need threading at all.

	  of libpthreads it was built with.
