  # From Linux arch/mips/Makefile
  #
  # GCC uses -G 0 -mabicalls -fpic as default.  We don't want PIC in the kernel
  # code since it only slows down the whole thing.  At some point we might make
  # use of global pointer optimizations but their use of $28 conflicts with
  # the current pointer optimization.
  #
  # The DECStation requires an ECOFF kernel for remote booting, other MIPS
  # machines may also.  Since BFD is incredibly buggy with respect to
  # crossformat linking we rely on the elf2ecoff tool for format conversion.
  #
  # cflags-y			+= -G 0 -mno-abicalls -fno-pic -pipe
  # cflags-y			+= -msoft-float
  # LDFLAGS_vmlinux		+= -G 0 -static -n -nostdlib
  # MODFLAGS			+= -mlong-calls
  #
  
  #
  # Meanwhile, U-Boot rely on PIC. We add proper switches explicitly.
