A better wording IMO:

	This option allows to customize the "vendor" part of the
	toolchain tuple, where the toolchain tuple has the form
	<cpu>-<vendor>-<kernel>-<os>. The default value, "buildroot",
	is fine for most cases, except in very specific situations
	where gcc might make different decisions based on the vendor
	part of the tuple. The value "unknown" is not allowed as the
	cross-compiling toolchain might then be confused with the
	native toolchain when the target and host architecture are
	identical.

	If you're not sure, just leave the default "buildroot" value.
