I think the variable that you want to match against (in the specific
case of cross.bbclass) is ${TARGET_SYS}.  Having the matching variable
be named COMPATIBLE_ARCH would imply that it's going to match
${HOST_ARCH}, which obviously isn't what you want.

I would have thought that confusion with ${MACHINE} should be minimal
since that nomenclature is already quite well established in OE.  But
you could name it COMPATIBLE_TARGET_SYS if you wanted to make the name
completely explicit.
