As far as I can tell, not all osmo-* programs do this yet.

Only the following have a BUILT_REFERENCE_XML in their Makefile.am:

osmo-bsc/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/bsc_vty_reference.xml
osmo-cbc/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/cbc_vty_reference.xml
osmo-gbproxy/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/gbproxy_vty_reference.xml
osmo-mgw/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/mgw_vty_reference.xml
osmo-msc/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/msc_vty_reference.xml
osmo-pcu/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/pcu_vty_reference.xml
osmo-sgsn/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/sgsn_vty_reference.xml
osmo-smlc/doc/manuals/Makefile.am:  BUILT_REFERENCE_XML = $(builddir)/vty/smlc_vty_reference.xml
