	  Explicitly specify what locales to install on target. If N
	  then all locales supported by packages are installed.

config BR2_ENABLE_LOCALE_WHITELIST
	string "Locales to keep"
	default "C en_US de fr"

	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

	  If your target CPU does not have a Floating Point Unit (FPU) or a
	  kernel FPU emulator, but you still wish to support floating point
	  functions, then everything will need to be compiled with soft
	  floating point support (-msoft-float).

config BR2_TARGET_OPTIMIZATION
	string "Target Optimizations"
	default "-pipe"
	help
	  Optimizations to use when building for the target host.
	  NOTE: gcc optimization level is defined in build options.

config BR2_TARGET_LDFLAGS
	string "Target linker options"
	help
	  Extra options to pass to the linker when building for the target.

config BR2_ECLIPSE_REGISTER
	bool "Register toolchain within Eclipse Buildroot plug-in"
	help
	  This options tells Buildroot to generate the necessary
	  configuration files to make your toolchain appear within
	  Eclipse, through the Eclipse Buildroot plugin.
