[bitbake-devel] [PATCH v4 15/18] bitbake, runqueue.py: Add -i to invalidate a stamp and rebuild the target

[Jason Wessel]

It is highly desirable to be able to invalidate a stamp used for
do_compile and to be able to continue on to build the entire
package's build rule.

If invalidating a stamp, the setscene rules for the specified targets
should be automatically canceled so as to allow a forced build
of an individual target.
