    gnu: avahi: Find 'TARGET-pkg-config' when cross-compiling.
    
    The configure script first tests whether "pkg-config" is in PATH,
    and then uses "TARGET-pkg-config".  Pretend "pkg-config" exists.
    
    * gnu/packages/avahi.scm (avah)[arguments]<#:configure-flags>: Set
      ac_cv_prog_have_pkg_config=yes when cross-compiling.
