config BR2_ENABLE_LOCALE_PURGE
	bool "Purge unwanted locales"
	help
	  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"
	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.

	  Generate support for a list of locales. Locales can be
	  specified with or without encoding, when no encoding is
	  specified, UTF-8 is assumed. Examples of locales: en_US,
	  fr_FR.UTF-8.

config BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_COPY
	bool "Copy gconv libraries"
	depends on BR2_TOOLCHAIN_USES_GLIBC
	help
	  The gconv libraries are used to convert between different
	  character sets (charsets).

	  Say 'y' if you need to store and/or display different charsets.

config BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_LIST
	string "Gconv libraries to copy"
	depends on BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_COPY
	help
	  Set to the list of gconv libraries to copy.
	  Leave empty to copy all gconv libraries.

	  Specify only the basename of the libraries, leave
	  out the .so extension. Eg.:
	    IBM850 ISO8859-15 UNICODE

	  Note: the full set of gconv libs are ~8MiB (on ARM).

# 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.

	  are unsure, just say Y.

config BR2_TARGET_OPTIMIZATION
	string "Target Optimizations"

	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.

	  Note that options with a '$' sign (eg. -Wl,-rpath='$ORIGIN/../lib')
	  are not supported.

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.

# Options for packages to depend on, if they require at least a
# specific version of the kernel headers.
# Toolchains should choose the adequate option (ie. the highest
# version, not all of them).
