app build:enhance apps to support independent out-of-tree builds

Browse source 
by defining the `PREFIX` variable and setting it to an external path,
`make -C /some/app` can be called independently to build a separate application out_tree.

modify Make.defs and Application.mk so that their dependent variables can be overwritten.
