[PATCH] ppc64 boot: remove sysmap from required filenames

A stripped vmlinux does not contain enough symbols to recreate the
System.map.  The System.map file is only used to determine the end of
the runtime memory size.  This is the same value (rounded up to
PAGE_SIZE) as ->memsiz in the ELF program header.

Also, the target vmlinux.initrd doesnt work in 2.6.14:

  arch/ppc64/boot/addRamDisk arch/ppc64/boot/ramdisk.image.gz vmlinux.strip arch/ppc64/boot/vmlinux.initrd
  Name of vmlinux output file missing.
