Hi, guys:

Would anybody take a tech review to my patch? Thanks!

the best,
thank you

This patch mainly aims to add optimisation for crosssdk setscene dependency
validating which we haven't handled in current logic, and which I think we
could have as we've already implemented to native/cross, although there
are albeit not many crossdk tasks, we could still get some performance
enhancement.

And it also fix a vulnerability of some certain workflow, think about the
following scenario with current logic:
     bitbake nativesdk-eglibc-initial -c cleansstate
     bitbake gcc-crosssdk-initial -c clean
     bitbake gmp-native -c clean
     bitbake libmpc-native -c clean
     bitbake mpfr-native -c clean
     bitbake gcc-crosssdk-initial
     bitbake nativesdk-eglibc-initial

Aboving will fail for absence of a few native libraries required by
gcc-crosssdk-initial.

Also modified some places in current code except the optimisation, as
following:
1 Remove isNative function since no code is referring it.
2 Add do_package to the list that don't exist and are noexec.
