6444d5806d
The change fixes installing for RTEMS 3rd Party packages where the RSB considered them Canadian Cross Compiling (Cxc). Fixing the Cxc issue broke real Cxc builds. The change corrects the issue of macros being changed in the Cxc and the prep data not being udpated. The configuration is loaded again after the updated macros. The macros are also copied and restored to ensure a clean stable base. The change also introduces --rtems-tools and --rtems-bsp to align the command line with the waf configure process or RTEMS application.
