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")
