[oe] [RFC] Zaurus: make updater.sh obsolete for poodle, clamshells and tosa

[Andrea Adami]

I probably did not explicit that actual Narcissus images cannot be
flashed on nand if renamed initrd.bin.
And the OE-built images have the 16bytes header thus cannot be flashed
'vanilla' using nandwrite.

We should abandon the
  cat ${STAGING_LIBDIR}/sharp-flash-header/header-c700.bin
we have now in zaurus-clamshel.inc during jffs image creation and remove the
  /sbin/bcut -s 16 -o $TMPHEAD $TARGETFILE
in updater.sh.

Dunno about retro-compatibility, though.
That headers cruft could be made distro-specific for sharp-compatible.

My 2 cents
