Sorry, they don't. They would if you had a full installation of gnatcoll
(as I have, with FSF GCC 7.1.0 for macOS).

Looks as though you need the source (from libre? certainly from github),
and provided your gnatcoll has projects, iconv and sqlite enabled it
should select xref automatically.

I suppose I must have iconv installed; anyway, the notes are as below
(adjust for obvious mac-isms! and you probably won't want/have gmp)

========================================================================
GNATColl built without changes. It was configured as below, which is
minimal apart from GNU Readline, GMP and Projects being enabled and
PostGres being disabled. Users may wish to reconfigure for their own
requirements.

  ./configure \
    --prefix=/opt/gcc-7.1.0 \
    --build=x86_64-apple-darwin15 \
    --enable-gpl \
    --with-gmp \
    --without-postgresql

(I'm not sure that --with-gmp is needed if the library is found)
resulting in

  Shared libraries:       yes (default: static)
  Gtk+:                   no (requires pkg-config and gtkada.gpr)
  Python:                 yes /System/Library/Frameworks/Python.framework/Versions/2.7 (see --with-python)
  PyGtk:                  no  (see --enable-pygtk)
  PyGObject:              no (see --enable-pygobject)
  Syslog:                 yes (see --enable-syslog)
  Readline (GPL license): yes (see --with-readline --enable-gpl)
  gmp:                    yes (see --with-gmp)
  PostgreSQL:             no (see --with-postgresql)
  Sqlite:                 embedded  (see --with-sqlite)
  Iconv:                  yes (see --with-iconv)
  Projects:               yes
