frv: clean up arch/frv/Makefile
Browse files Browse the repository at this point in the history
- removed a lot of unused variable assignmnets
- removed unused bootstrap target
- replaced ARCHMODFLAGS with proper KBUILD_{A,C}FLAGS_MODULE assignmnets

The resuting Makefile has not been tested due to lack of toolchain,
but these were all trivial changes.
