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.
