I prefer to use hyphens, when possible (GNU make only),
but obviously that is not portable to all Make programs.
So, when I remember that maint.mk is used only if/when GNU Make
is available, I tend to use hyphen -- assuming it's used only in that
file, and not used in any Makefile.am.  I suspect that some pieces of
that file migrated from Makefile.am, where portability dictated
the use of underscores.
