    tools: Use PKG_CONFIG_FILE instead of PKG_CONFIG variable
    
    Replace PKG_CONFIG variable name with PKG_CONFIG_FILE for the name of
    the pkg-config file.
    This is preventing a conflict in some build systems where PKG_CONFIG
    actually contains the path to the pkg-config executable to use, as the
    default assignment in libs.mk is using a weak assignment (?=).
    
    This problem has been found when trying to build the latest version of
    Xen tools using buildroot.
    
    Fixes: d400dc5729e4 ("tools: tweak tools/libs/libs.mk for being able to 
support libxenctrl")
