    stubdom: introduce xenlibs.mk
    
    This new makefile will be used to build libraries that provides
    "Makefile.common".
    
    At some point, we will be converting Makefile in tools/ to "subdirmk"
    and stubdom build will not be able to use those new makefiles, so we
    will put the necessary information for stubdom to build the xen
    libraries into a new Makefile.common and xenlibs.mk will use it.
    We only need to build static libraries and don't need anything else.
    
    The check for the presence of "Makefile.common" will go aways once
    there is one for all libraries used by stubdom build.
    
    Also remove DESTDIR= from "clean" targets, we don't do installation in
    this recipe so the value of DESTDIR doesn't matter.
