I've merged this one, thanks.

I understand the need for this but I don't like the implementation :)

We can't use OEROOT here as its not a standard variable and is
deprecated. I was initially thinking POKYBASE but that isn't right
either in bitbake. Hmm.

Chris, any suggestions? I'm actually struggling a bit to come up with a
variable that represents a "head" of the metadata :/. Perhaps filename
would be enough in this case?

I'd also suggest we remove this path when we save the siginfo file, not
when we load it and do the comparison.

Why the initial:

if self.twl and not self.twl.search(dataCache.pkg_fn[fn]):

?

I suspect it should just be:

dep_fn = re.search("(?P<fn>.*)\..*", dep).group('fn')
if self.twl.search(dataCache.pkg_fn[dep_fn]):
    #bb.note("Skipping %s" % dep)
    continue

?

For native/cross tasks, I still expect then to have dependencies and be
rebuilt if something changes, I just don't expect target packages to
change when native/cross ones do.

Cheers,

Richard
