Looks like it is complaining about virFileClose(), plus
virFilePrint() in the full output, as well. So maybe linking against
libvirt.la is needed after all?

If there's no harm in that, how about defining

  MOCKLIBS_LDADD = \
    $(GNULIB_LIBS) \
    ../src/libvirt.la

and using it for every mock library, like the existing
$(MOCKLIB_LDFLAGS)?

Cheers.
