openmpi/config/opal_check_os_flavors.m4
Jeff Squyres b29b852281 Consolidate all the opal/orte/ompi .m4 files back to the top-level
config/ directory.  We split them apart a while ago in the hopes that
it would simplify things, but it didn't really (e.g., because there
were still some ompi/opal .m4 files in the top-level config/
directory, resulting in developer confusion where any given m4 macro
was defined).

So this commit consolidates them back into the top-level directory for
simplicity.  

There's still (at least) two changes that would be nice to make:

 1. Split any generated .m4 file (e.g., autogen-generated .m4 files)
    into a separate directory somewhere so that a top-level -Iconfig/
    will only get our explicitly defined macros, not the autogen stuff
    (e.g., with libevent2019 needing to get the visibility macro, but
    NOT all the autogen-generated inclusion of component configure.m4
    files).
 1. Change configure to be of the form:
{{{
# ...a small amount of preamble/setup...
OPAL_SETUP
m4_ifdef([project_orte], [ORTE_SETUP])
m4_ifdef([project_ompi], [OMPI_SETUP])
# ...a small amount of finishing stuff...
}}}

I doubt we'll ever get anything as clean as that, but that would be
the goal to shoot for.
