	select BR2_LARGEFILE
	help
	  Enable this option if you want your toolchain to support
	  files bigger than 2 GB.

config BR2_TOOLCHAIN_BUILDROOT_INET_IPV6
	bool "Enable IPv6 support"
	select BR2_INET_IPV6
	help
	  Enable this option if you want your toolchain to support
	  IPv6.

config BR2_TOOLCHAIN_BUILDROOT_INET_RPC
	bool "Enable RPC support"
	select BR2_TOOLCHAIN_HAS_NATIVE_RPC
	help
	  Enable this option if you want your toolchain to support
	  RPC (needed for NFS, for example).

config BR2_TOOLCHAIN_BUILDROOT_WCHAR
	bool "Enable WCHAR support"
	select BR2_USE_WCHAR
	help
	  Enable this option if you want your toolchain to support
	  wide characters (i.e characters longer than 8 bits, needed
	  for locale support).

	bool "Enable toolchain locale/i18n support"
	select BR2_TOOLCHAIN_BUILDROOT_WCHAR
	select BR2_ENABLE_LOCALE
	help
	  Enable this option if you want your toolchain to support
	  localization and internationalization.

	  Use this option to select the thread library implementation

	  threading at all.

	  Setting this option will enable the "-mfpu=vfp" option.
	  If your ARM CPU has a Vector Floating Point Unit (VFP)
	  and the toolchain supports the option, then the
	  code can be optimized.
