Yes, if I run "make defs.inc" in the doc directory, it works fine.
However, if I run "make all", it doesn't even build mkdefsinc nor
defsincdate.

Apparently, there is no dependency from *.info to defs.inc.  I'm
attaching a log of 'cd doc && make'.  If you need more detailed output
(e.g make -d), let me know.  I'm using Automake 1.14.1.

If I replace defs.inc with version.texi in gnupg.texi, Automake emits
the following rules to Makefile.in:

  $(srcdir)/gnupg.info: gnupg.texi $(srcdir)/version.texi $(gnupg_TEXINFOS)
  gnupg.dvi: gnupg.texi $(srcdir)/version.texi $(gnupg_TEXINFOS)
  gnupg.pdf: gnupg.texi $(srcdir)/version.texi $(gnupg_TEXINFOS)
  gnupg.html: gnupg.texi $(srcdir)/version.texi $(gnupg_TEXINFOS)

So, I think, if you rename the file, you need to manually add
the dependencies, or maybe add defs.inc to BUILT_SOURCES, which should
be built before other rules (it works fine here).
