[PATCH] ppc32 ld.script fix for building on ppc64

[Al Viro]

	In arch/ppc/boot/ld.script we need OUTPUT_ARCH(powerpc:common) for
the same reasons why we need it in vmlinux.lds.S; when we build on ppc64
box, we need to be explicit about the target.
	See http://linus.bkbits.net:8080/linux-2.5/cset@1.1784.8.10 for
the corresponding fix in vmlinux.lds.S.
