Hmm, I got this from my Linux Build.
I thought it was odd and left it out and it did not work, got the  
wrong symbol names.
I think it has something to do with function descriptors.

ahh I see th problem now, arch/powerpc/Makefile, line 42:
  ifeq ($(CONFIG_PPC64),y)
  OLDARCH       := ppc64
  SZ    := 64

  new_nm := $(shell if $(NM) --help 2>&1 | grep -- '--synthetic' > / 
dev/null; then echo y; else echo n; fi)
  ifeq ($(new_nm),y)
  NM            := $(NM) --synthetic
  endif

I'll do the same thing, Sorry hollis.
