Because they are not needed to build VLC itself

Last time I tried it worked, check the buildbot logs and compare to
your setup

BTW linking to libvlccore is an error, npapi (and activex) should only
depend on libvlc, perhaps libvlccore is pulling the edpendancy on
libgpg-error through the libtool archives?
