    tools: add link path flag for local build to pkg-config files
    The qemu build process is requiring the link path of Xen libraries
    to be specified both with -L and -Wl,-rpath-link. Add the -L flag
    to the local pkg-config files.
    At the same time let the pkg-config files depend on the Makefile
    creating them, too.
