    sstate: avoid indirect bison/flex-native dependencies (via SSTATE_EXCLUDEDEPS_SYSROOT)
    
    Avoid adding flex-native or bison-native to the sysroot without a specific
    dependency in the recipe. This means indirect dependencies
    (e.g. X -> Y -> binutils-cross -> flex-native) no longer meet the
    dependency incidentally. This improves determinism and avoids build
    failures when people switch to external toolchains.
    
    Based on an idea by Richard Purdie:
