In GNU MPFR, we have a comment giving the form of the triple for each
MPFR version:

#         MPFR     -version-info
#        2.1.x      -
#        2.2.x    1:x:0
#        2.3.x    2:x:1
#        2.4.x    3:x:2
#        3.0.x    4:x:0
#        3.1.x    5:x:1
#        4.0.x    6:x:0
libmpfr_la_LDFLAGS = $(MPFR_LDFLAGS) $(LIBMPFR_LDFLAGS) -version-info 6:0:0

and I've written a Perl script tools/ck-version-info that parses this
comment and checks that the values changes in a way that is consistent
with the libtool rules and that the -version-info value corresponds to
the form associated with the MPFR version. This script is run by
"make dist" via a dist-hook, so that before a release, one ensures
consistency and one keeps a trace of the history.
