    # Ensure that the binary we just built can find liblutok.  This is
    # needed because the lutok.pc file (which the Makefile used above
    # queries) does not provide rpaths to the installed library and
    # therefore the binary may not be able to locate it.  Hardcoding the
    # rpath flags into lutok.pc is non-trivial because we simply don't
    # have any knowledge about what the correct flag to set an rpath is.
    #
    # Additionally, setting rpaths is not always the right thing to do.
    # For example, pkgsrc will automatically change lutok.pc to add the
    # missing rpath, in which case this is unnecessary.  But in the case
    # of Fedora, adding rpaths goes against the packaging guidelines.
