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.]
