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.
