Avoid adding bison-native to the sysroot without a specific
dependency in the recipe. This means indirect dependencies
(e.g. X -> Y -> binutils-cross -> bison-native) no longer meet the
dependency incidentally. This improves determinism and avoids build
failures when people switch to external toolchains.
