[Martin Jansa <martin.jansa@gmail.com>]

* some packages have .ko files which are not elf, without this change
  it fails with TypeError, with this change only runstip fails and
  reports where:
  ERROR: runstrip: ''arm-oe-linux-gnueabi-strip'  '/OE/shr-core/tmp-eglibc/work/armv4t-oe-linux-gnueabi/emacs-23.4-r0/package/usr/share/emacs/23.4/etc/tutorials/TUTORIAL.ko'' strip command failed
