Gregory Nutt d1a8a803e4 Build system: Get rid of the MOVEOBJ definition 
Eliminate the MOVEOBJ definition from tools/Config.mk, Makefiles, and other locations.  The MOVEOBJ definition was used to work around the case where the object output of a compile or assemble is in a different directory than the source file.  The ZDS-II tools have no command line option to perform this move; MOVEOBJ handled the move as a post-compiler operation.

MOVEOBJ is no longer needed because this the ez80 COMPILE and ASSEMBLE definitions now handle all of the object file movement cases.
