toolchain: control vendor part in GNU_TARGET_NAME 



This option allows to customize the "vendor" part of the
toolchain tuple, where the toolchain tuple has the form
<arch>-<vendor>-<os>-<libc>. Use this option in situations
where gcc might make different decisions based on the vendor
part of the tuple.

[Thomas: move the config option in a slightly different place, so that
it does not appear between the C library selection and the C library
options.]

	  This option allows to customize the "vendor" part of the

	  toolchain tuple, where the toolchain tuple has the form

	  <arch>-<vendor>-<os>-<libc>. 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. The value can not be empty either.



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