MIPS: Refactor arch/mips/boot/compressed/Makefile
- use hostprogs-y for the elf2ecoff - list all *.o file in targets - renamed obj-y to vmlinuzobjs-y (it was confusing to re-use a kbuild variable) - fix all uses of if_changed/cmd - use kbuild rules to beautify output - update clean-file to clean vmlinuz.* in top-level directory - simplied logic in arch/mips/Makefile for compressed targets The net result is a more kbuild conformant Makefile but readability did not increase.
