Re: [PATCH 0/6] mips: diverse Makefile updates

Hi, Sam & Ralf

Perhaps we also need to fix the following stuff:

...
  LD      vmlinux
  SYSMAP  System.map
  SYSMAP  .tmp_System.map
mips64el-unknown-linux-gnu-objcopy -O elf32-tradlittlemips  --remove-section=.reginfo vmlinux vmlinux.32
  AS      arch/mips/boot/compressed/head.o
  CC      arch/mips/boot/compressed/decompress.o
  CC      arch/mips/boot/compressed/dbg.o
...

The related Makefile is arch/mips/Makefile:

> 721 #
> 722 # Some machines like the Indy need 32-bit ELF binaries for booting purposes.
> 723 # Other need ECOFF, so we build a 32-bit ELF binary for them which we then
> 724 # convert to ECOFF using elf2ecoff.

> 734         $(OBJCOPY) -O $(64bit-bfd) $(OBJCOPYFLAGS) $< $@
