[XEN PATCH v9 14/30] build: remove KBUILD_ specific from Makefile.host

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

This will allow $(HOSTCFLAGS) to actually be used when building
programmes for the build-host.

The other variable don't exist in our build system.

Also remove $(KBUILD_EXTMOD) since it should always be empty.
