openmpi/ompi/config/ompi_setup_mpi_profiling.m4
Ralph Castain 214e26b539 Per Jeff (this work was done on a branch of mine, so I will do the commit):
Re-enable "./autogen.sh -no-ompi" again. If you -no-ompi, the entire OMPI
configury is skipped and the entire ompi/ subtree is not built. There's
some simple m4-isms that prune out the relevant parts.

I added ompi/config/, orte/config/, and opal/config/ directories. I moved a
bunch of m4 files from the top-level config/ dir into ompi/config/, and a few
into orte/config/.

Note that all 3 <project>/config directories have a config_files.m4 file. This
file contains the AC_CONFIG_FILES list for that project. The AC_CONFIG_FILES
call cannot be in an AC_DEFUN macro and conditionally called -- if it is
included at all, Autoconf will process it. Hence, these config_files.m4 files
don't AC_DEFUN -- they just have AC_CONFIG_FILES. m4_ifdef() is used to
conditionally include the files or not.

I moved a bunch of obvious OMPI-only m4 files from config/ to ompi/config/,
but I'm sure that there's more that could go. A ticket will be filed with
thoughts on future work in this area.
