Nope, that change had been later reverted, before any stable release:
<http://git.sv.gnu.org/gitweb/?p=automake.git;a=commit;h=v1.11-512-g40c3432>

This rules is there also for makefiles generated by Automake 1.12.x.

And the issue here is really not Automake's fault; the problem really likes in
the coreutil's build system, since the declaration:

   doc/constants.texi: $(top_srcdir)/src/tail.c $(top_srcdir)/src/shred.c

is hand-written in 'doc/local.mk', and is not provided by Automake.

So what suggested by the OP is not a workaround, but a fix -- and it
seems a correct fix to me (albeit a little abusing of Automake's
internal).

How so?  I see:
<http://git.savannah.gnu.org/gitweb/?p=automake.git;a=commit;h=v1.12>

See above.
