In some cases, it may make more sense to have the logic inverted and have the recipe always forbidden except for hand-picked machines. Such could be the case for pieces of software that only support some architectures. In that scenario, it is sometimes a bit easier on the eye and for maintenance to use the OVERRIDES mechanism but for that, a default should be set. COMPATIBLE_MACHINE:aarch64 = "^(aarch64)$" COMPATIBLE_MACHINE:mips64 = "^(mips64)$" wouldn't do much because if COMPATIBLE_MACHINE isn't set, the recipe is assumed compatible and therefore, if no default is provided we enter that case. Hence, we need to add COMPATIBLE_MACHINE = "^$" as default so that it only matches the empty string, which isn't possible for MACHINEOVERRIDES.
