Right thing to do. Not 100% sure I like the means, but I love the sentiment.

Tested on the Cavium in Sentex.

I would expect we could do something similar on riscv, and maybe arm.

I've been looking at something similar in D5572 to fix WITHOUT_SYMVER to turn off __sym_compat unconditionally.

I think we probably want a combination of the two with a MIN_COMPAT_RELEASE or similar variable and a series of COMPAT# defines.

I agree that sounds like a good further refinement but think this looks like a reasonable start. I'll probably also commit the Makefile changes from D5572.
