	  Directory to store all the source files that we need to fetch.

config BR2_STAGING_DIR

	default "$(BUILD_DIR)/staging_dir"
	help
	  This is the location where the toolchain will be installed.  The
	  toolchain will not work if it is moved from this location.
	  Therefore, if you wish to package up a uClibc toolchain, it is
	  important that is is set to the final location where the toolchain
	  will be used.

	  Most people will leave this set to the default value of
	  "$(BUILD_DIR)/staging_dir".

config BR2_GNU_BUILD_SUFFIX

	  The string used to pass to configure scripts via the

	  arch will be filled in automatically.

	string "GNU target suffix"
	default "nuttx-elf" if !BR2_ARM_EABI
	default "nuttx-eabi" if BR2_ARM_EABI
	help
	  The string used to pass to configure scripts via the
	  --target= option.  Just specify the suffix here, the leading
	  arch will be filled in automatically.

	  Most users will want to stick with the default setting, though
	  other users (most notably ARM EABI) like to add on to this in
	  order to stay in line with gcc conventions.

config BR2_PREFER_IMA
	bool "prefer IMA compiles"
	default n
	help
	  Where possible, compile package with Inter Module Analysis.
	  This potentially uses alot of system resources on your compile
	  host with the benefit of creating smaller binaries for the target.

	  If unsure, say No.

	  WARNING: This is highly experimental at the moment.
