We do something like that in the Junos build

prog makefile might have DPLIBS+= ${LIBFOO}
which is exactly equivalent to

LDADD+= -lfoo
DPADD+= ${LIBFOO}

but ensures that they stay in sync (not so important now with meta
mode).

bsd.libnames.mk can then have

DPLIBS_libfoo += ${LIBGOO}
DPLIBS_libgoo += ${LIBZOO}

All of which is processed by dpadd.mk which you can find in
contrib/bmake/mk
Though dpadd.mk ignores DPLIBS_libgoo += ${LIBZOO} if LIBZOO has already
been added.
