"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.inc instead of repeating the relevant line
in different recipes, but Richard was concerned about potential
side-effects in other usages of cross.inc.
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.
