We usually promise backwards compatibility with respect to accepted options
which is why we have things like

ftree-vect-loop-version
Common Ignore
Does nothing. Preserved for backward compatibility.

the backend errors on unknown march/tune and that would be a regression
for build systems using that (even if that's indeed very unlikely).  That's why
I suggested to make it still do something (doing "nothing", aka keeping generic
is probably worse than dropping).  I guess having -march=knl behave differently
is also bad so I guess there's not a good solution for that.

So - just to have made the above point, I'm fine with what x86 maintainers
decide here.
