scons: Break make_obj into make_static and make_shared functions.

The make_obj function took a boolean value which just selected which
of the two lines it in would actually do something. This change breaks
it into two lambdas, make_static and make_shared, which just do
whichever line would have been requested, making the funciton name more
self descriptive and getting rid of the generally unnamed and opaque
boolean argument.
