Why do you need both?  Surely COMPATIBLE_TARGET_ARCH can be implemented
by testing against COMPATIBLE_TARGET_SYS with a suitable wildcard.

TARGET_SYS only has real meaning for cross recipes.  For standard host
recipes, the variable to check would be HOST_SYS (via COMPATIBLE_HOST).
I'm not sure that putting cross-specific stuff in base.bbclass is a
wholesome plan.
