Details:

The Makefile rules for autogen-erating Makefile.util.am are not
the same as in autogen.sh:

* autogen.sh:
  cat $UTIL_DEFS | autogen -T Makefile.tpl | sed -e '/^$/{N;/^\n$/D;}' > ...

* conf/Makefile.common:
  autogen -T $(top_srcdir)/Makefile.tpl $< | sed -e '/^$$/{N;/^\\n$$/D;}' >
...

This leads to a build failure when touching gentpl.py:

$ ./autogen.sh && ./configure
$ touch gentpl.py
$ make
python gentpl.py | sed -e '/^$/{N;/^\\n$/D;}' > Makefile.tpl.new || (rm -f
Makefile.tpl.new; exit 1)
mv Makefile.tpl.new Makefile.tpl
autogen -T ./Makefile.tpl Makefile.util.def | sed -e '/^$/{N;/^\\n$/D;}' >
Makefile.util.am.new || (rm -f Makefile.util.am.new; exit 1)
mv Makefile.util.am.new Makefile.util.am
