That would, I expect, fix this particular problem, yes. To my taste,
it smacks of an ugly hack, though.

Usually, a cleaner solution is using AM_MAINTAINER_MODE; you seem to
patch it into configure.ac, but not in configure... So my suggestion
would be to put the add-maintainer-mode patch BEFORE the relibtoolise
patch, and then regenerate the relibtoolise patch (so that
AM_MAINTAINER_MODE is active when this patch regenerates ./configure
and the Makefile.in's, and then AM_MAINTAINER_MODE is actually active).
