[bitbake-devel] [PATCH] Revert "runqueue.py: Ensure one setscene function doesn't mask out another which needs to run"

[Richard Purdie]

This reverts commit b22592af8145a8c7c4ada2fa7c1dee2e753eca46.

That commit isn't entirely clear about why this change is needed but
I do have a usecase where this breaks things. If for example you run
"bitbake X -c packagedata" and that packagedata is in sstate, you'd 
expect this to work. 

If sstate doesn't contain a do_populate_sysroot for a dependency, you
would still expect the command above to succeed and you would not
expect
it to rebuild that dependency. With the current code, this isn't what 
happens. The code finds the sstate for do_populate_sysroot missing, 
this makes the task "uncovered" and this in turn makes it unskippable.

The example I found with this was avahi-ui, where it would trigger 
a build of libdaemon to obtain its populate_sysroot.

Since this behaviour seems completely incorrect, revert the older patch
and we'll address any issues that crop up as a result.
