The rules to make GUPnPIgd-1.0.gir don't declare a dependency on libgupnp-igd-1.0.la which means that when running under 'make -j' it's possible that make will try to build the GIR before the library is done.

That looks like this:

  GISCAN GUPnPIgd-1.0.gir
  CCLD   libgupnp-igd-1.0.la
libtool: link: cannot find the library `libgupnp-igd-1.0.la' or unhandled argument `libgupnp-igd-1.0.la'
