You should add the buildaction attribute the to the object file, not the
executable.  But that is only a workaround for the real problem.

This is similar to a problem I noticed with C++: The buildaction
attribute is added to an object file when it is compiled.  When the
building is to be done, the buildaction of all object files is checked
and used.  But if the object was not compiled then there is no
buildaction attribute.

This is a problem if building is done for another reason than the object
file having changed.  For example, when you delete the executable.

The solution should be that the buildaction attribute is added when the
dependency is setup, not when the action is invoked.  But that means we
need a new mechanism.  Does someone have an idea how this should be done?
