ARC: Assume multiplier is always present
[ Upstream commit 0eca6fdb3193410fbe66b6f064431cc394513e82 ] It is unlikely that designs running Linux will not have multiplier. Further the current support is not complete as tool don't generate a multilib w/o multiplier. Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
