    tools: correct tools/tests/depriv/Makefile
   
    tools/tests/depriv/Makefile directly builds the target program from
    its C-source. This is problematic when an incremental build is needed
    after a header the program is depending on has been modified: in this
    case all headers are added into the gcc call and the build will fail.
   
    Correct that by adding a rule for building the program from its .o
    file.
