On some systems (Gentoo) configure stage fails because of docbook2man
working with SGML rather than with XML. We don't need xmlwf man pages so
we disable this.

In addition to the default little-endianness format, I added a mode
so that we can generate firmware with big-endianness format.

The current make-ras.sh image generation script for the ZyXEL NBG6617
has portability issues with bash. Because of this, factory images are
currently not built correctly by the OpenWRT buildbots.

This commit replaces the make-ras.sh by C-written mkrasimage.

The new mkrasimage is also compatible with other ZyXEL devices using
the ras image-format.
This is not tested with the NBG6616 but it correctly builds the
header for ZyXEL factory image.

This adds a tool to generate a firmware file accepted
by Netgear or sercomm devices.

They use a zip-packed rootfs with header and a custom
checksum. The generated Image can be flashed via the
nmrpflash tool or the webinterface of the router.
