ppc64 gcc-3.4.2 lk-2.6.10-rc1-mm4 link errors

[Doug Maxey]

Same compiler (3.4.2) with updated binutils, but this time with
mainline kernel, gets link errors on final kernel zImage.

'make vmlinux' does complete _without_ errors.

Have I created a monster by missing some flags?

BTW, ld apparently does not return error, so the make just blasts on
by.
