    recipes/*-cross recipes: ignore TARGET_ARCH sstate hash
    
    "yocto-compat-layer.py --machines" showed that shared packages like
    gcc-cross-powerpc64 have a sstate signature that depends on
    TUNEFLAGS. As a result, there are unnecessary rebuilds and potential
    conflicts in a multiconfig.
    
    That's due to the way how TARGET_ARCH is set. Richard Purdie suggested
    setting TARGET_ARCH[vardepvalue] as fix, which works. It would be
    shorter to do that in cross.bbclass instead of repeating the relevant
    line in different recipes, but Richard was concerned about potential
    side-effects in other usages of cross.bbclass.
    
    TARGET_GOARM as used in go.inc is still causing signature differences
    for go-cross-powerpc64 and machines b4420qds-64b and p5020ds-64b. This
    needs further investigation.
