Since we're now 32-bit "armv" only, we don't need to select the
linker script in vmlinux.lds.S.  Also, whoever moved vmlinux.lds.S
into arch/arm/kernel forgot to move the other scripts.

This cset replaces arch/arm/kernel/vmlinux.lds.S with
arch/arm/vmlinux-armv.lds.in, and deletes the obsolete scripts.
