toolchain: control vendor part in GNU_TARGET_NAME
PATCH v4 1/1 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.

Overly-long line, please wrap at <80 chars.
(Or maybe your mailer is broken?)
