6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <antonb@xxxxxxxxxxxxxxx>
[ Upstream commit 5ba7a75a53dffbf727e842b5847859bb482ac4aa ]
A recent change to gcc flags rv64iv as no longer valid:
cc1: sorry, unimplemented: Currently the 'V' implementation
requires the 'M' extension
and as a result vector support is disabled. Fix this by adding m
to our toolchain vector detection code.
