Improvements to AAsmModule shared makefile
Ben Avison authored
Detail:
  * Corrected and added documentation at head of file
  * Now defines an "all" target
  * DIRS now has a default value (i.e. behaviour now matches the other shared
    makefiles) freeing the master makefile from needing to specify platform-
    specific paths
  * Added cross-compilation version
Admin:
  Tested by cross-compiling the BASIC module
