Instead of solving the problem to deliver ROM modules to core while booting differently for the several kernels (multi-boot, elfweaver, core re-linking), this commit unifies the approaches. It always builds core as a library, and after all binaries are built from a run-script, the run-tool will link an ELF image out of the core-library and all boot modules. Thereby, core can access its ROM modules directly. This approach now works for all kernels except Linux. With this solution, there is no [build_dir]/bin/core binary available anymore. For debugging purposes you will find a core binary without boot modules, but with debug symbols under [run_dir].core. Fix #2095
