configury: fix autogen.pl --no-ompi

The Makefile.ompi-rules trim options previously used AM_CONDITIONALs
that were defined only when the OMPI project was configured.  Hence,
if you ran "autogen.pl --no-ompi", autogen would fail with lots of
messages about undefined AM_CONDITIONALs.

This commit makes new AM_CONDITIONALs outside of the project
configuration that can be safely used elsewhere.
