Ahh... that must be it, then.

So I suppose the modules that now use AC_PROG_MKDIR_P
should instead depend on a new module that provides an
AC_PROG_MKDIR_P work-alike (via a new gnulib/m4/mkdir-p.m4)
for people using older versions of autoconf.

That is, *if* gnulib needs to support autoconf older than 2.60.
Do any of you know of gnulib-using projects that require
autoconf 2.59 or older?
