    tools: add pkg-config file for libxc
    
    When configuring the build of qemu the configure script is building
    various test programs to determine the exact version of libxencontrol.
    
    Instead of a try and error approach needing updates for nearly each
    new version of Xen just provide xencontrol.pc to be used via
    pkg-config.
    
    In the end we need two different variants of that file: one for the
    target system where eventually someone wants to build qemu, and one
    for the local system to be used for building qemu as part of the Xen
    build process.
    
    The local variant is created in a dedicated directory in order to be
    able to collect more pkg-config files used for building tools there.
