Many configure scripts support an option like --disable-doc, --disable-docs
or --disable-documentation. Pass all of these to configure.
In addition, not all Xorg packages accept the --disable-xxx. Instead they
look for xmlto and/or fop and build documentation if they exist. For host
packages, this may lead to build errors because /usr/bin/xmlto uses libxml2
and we set LD_LIBRARY_PATH to point to $(HOST_DIR)/lib, which may contain
a libxml2 as well. So it's essential to disable xmlto for host packages.
Also some whitespace cleanup.
