#     powerpc/32: Move the old 6xx -mcpu logic before the TARGET_CPU logic
#     
#     The code:
#     
#       ifdef CONFIG_6xx
#       KBUILD_CFLAGS          += -mcpu=powerpc
#       endif
#     
#     was added in 2006 in commit f48b8296b315 ("[PATCH] powerpc32: Set cpu
#     explicitly in kernel compiles"). This change was acceptable since the
#     TARGET_CPU logic was 64-bit only.
#     
#     Since commit 0e00a8c9fd92 ("powerpc: Allow CPU selection
#     also on PPC32") this logic is no longer acceptable after the TARGET_CPU
#     specific. It currently appends -mcpu=powerpc at the end of the command
#     line, after any TARGET_CPU specific:
#     
#       gcc -Wp,-MD,init/.do_mounts.o.d ...
#         -mcpu=powerpc -mbig-endian -m32 ...
#         -mcpu=e300c2 ...
#         -mcpu=powerpc ...
#         ../init/do_mounts.c
#     
#     Fixes: 0e00a8c9fd92 ("powerpc: Allow CPU selection also on PPC32")
