Looks like this was mistakently removed in the conversion to PRRTE.
We still need CFLAGS_WITHOUT_OPTFLAGS for Open MPI's MPI debugger
interface. Not having this functionality means that ompi/debuggers
was being compiled incorrectly, which led to -- among other things --
32 bit builds failing.

Temporary solution for the PML inconsistency issue discussed in #7475.
This patch address 2 things: first it make the PMIx key optional so that
if we are not in a full modex mode we don't do a direct modex, and
second it get the PML info from the vpid 0 instead of from the local
rank.

Restrict the search to the "immediate" range so at worst we check with
our local server and don't go up to the host daemon.

- Deal with deprecated cmd line options and rndz files
- Protect against DVM collisions
- Update atomics
- Fix fork/exec and provide better tool support (PMIx)
- Ensure we cleanup completely upon terminating a tool/server that has
dropped rendezvous files
- Fix multithreaded launch race on remote node
- Fix bug where multiple threads can be modifying app->env
- Add a --no-ready-msg option to prte
- Utilize the PMIx_Spawn ability to do a fork/exec on our behalf to better
setup the "prte" DVM when running in proxy mode
- Provide better isolation between DVM instances
- Fix race condition in shutdown of PMIx fork/exec framework
- Ensure ompi personality gets added in proxy scenarios

This commit contains the following changes:
The C++ bindings were removed from the standard in MPI-3.0. This
commit removes the entirety of the C++ bindings as well as the
support configury.
Removes all references to C++ from the man pages. This includes the
bindings themselves, all references to what C++ bindings return,
all not-available comments, and differences between C++ and other
language bindings.
If the user passes --enable-mpi-cxx, --enable-mpi-cxx-seek, or
--enable-cxx-exceptions, print a warning message an abort configure.

This commit removes the specialized support for Sparc v9 as the
architecture is unsupported. The architecture will continue to
work without CMA and using the GCC built-in atomic support.

This commit removes the unsupported __sync built-in atomics in
favor of the GCC built-ins. The priority order (if not modified
by configure flags) is: C11, custom atomics
(opal/include/opal/sys/*), then GCC built-ins.

IA64 atomic support was deleted some time ago. Some of the references
to the architecture were not removed when the atomic support was. This
commit removes those lingering references. IA64 will continue to work
unsupported with the built-in atomics.

Before this change, the reference counters `opal_util_initialized`
and `opal_initialized` were incremented at the beginning of the
`opal_init_util` and the `opal_init` functions respectively.
In other words, they were incremented before fully initialized.
This causes the following program to abort by SIGFPE if
`--enable-timing` is enabled on `configure`.
```c
// need -lm option on link
int main(int argc, char *argv[])
{
// raise SIGFPE on division-by-zero
feenableexcept(FE_DIVBYZERO);
MPI_Init(&argc, &argv);
MPI_Finalize();
return 0;
}
```
The logic of the SIGFPE is:
1. `MPI_Init` calls `opal_init` through `ompi_rte_init`.
2. `opal_init` changes the value of `opal_initialized` to 1.
3. `opal_init` calls `opal_init_util`.
4. `opal_init_util` calls `opal_timing_ts_func` through
`OPAL_TIMING_ENV_INIT`, and `opal_timing_ts_func` returns
`get_ts_cycle` instead of `get_ts_gettimeofday` because
`opal_initialized` to 1.
(This is the problem)
5. `opal_init_util` calls `get_ts_cycle` through
`OPAL_TIMING_ENV_INIT`.
6. `get_ts_cycle` executes
`opal_timer_base_get_cycles()) / opal_timer_base_get_freq()`
and it raises SIGFPE (division-by-zero) because the OPAL TIMER
framework is not initialized yet and `opal_timer_base_get_freq`
returns 0.
This commit changes the increment timing of `opal_util_initialized`
and `opal_initialized` to the end of `opal_init_util` and the
`opal_init` functions respectively.

The SM BTL was effectively removed a long time ago. All that was left
was a shell that warned people if they tried to use the SM BTL. For
v5.0, we plan to finally remove this ancient shell (and possibly
replace it with vader).

External pmix installs are frequently in non-standard locations and
the path to their shared libraries are not ldconfig'd in because
there may be multiple pmix installs.
The way the configury was set up prior to this patch, the configuration
would fail soon after the PMIX config stuff was called because it
added some pmix lib stuff to the LDFLAGS, resulting in configury tests
for things that require running the configure test to fail.
This patch avoids this problem by resetting the LDFLAGS and LIBS back
to what they were prior to the run of the external PMIX detection.
The CFLAGS setting is left because there are many places in the ompi
and opal source code where pmix_common.h needs to be included.
