Seems the elf_platform () returned strings need some adjustment to match the
RS6000_CPU names. Grepping Linux kernel, elf_platform can return e.g.
pa6t
power3
power4
power5
power5+
power6
power6x
power7
power7+
power8
powerpc
ppc403
ppc405
ppc440
ppc440gp
ppc470
ppc5554
ppc601
ppc603
ppc604
ppc7400
ppc7450
ppc750
ppc823
ppc8540
ppc8548
ppc970
ppca2
ppc-cell-be
ppce500mc
ppce5500
ppce6500
so, supposedly initialy "ppc" prefix, if any, should be dropped, "ppc-cell-be"
should be replaced by "cell" and most likely the string checked against the
asm_names[].cpu strings. There are other minor differences, e.g. kernel has
ppc440 and ppc440gp, while gcc 440fp and 440 (do they match in this order, or
differently?).
