This adds fixes to the stub domain build into compiling Ian Jackson's qemu-xen. The most notable change is that mini-os headers now #include each other through a mini-os/ prefix, so that we can turn all -I into -isystem and still be sure that we include Mini-OS headers (and not qemu's console.h or blktaplib's list.h for instance...).
