The linker of Linux/AArch64 (at least) generates `__bss_start__`,
`__bss_end__`, `_bss_end__`, and `__end__` symbols.
`libmpi_usempi_ignore_tkr.so` is added but `libmpi_usempif08.so`
is not added because `use-mpi-f08` has `contains` statements
in modules and compilers automatically generate compiler-specific
symbols for them. For example, gfortran 4.9 generates
`__mpi_f08_callbacks_MOD_mpi_comm_dup_fn` etc.

Change the default enable configure option XRC to disabled. If a user want's
to give it a try they have to explicitly ask for it.
Modify the configury help message to indicate it is not enabled by default.

Every modern compiler supports either inline assembly or builtin atomic
operations. Because of this it is time to delete all the code associated
with pre-built atomics.
This commit also clean out the DEC and XLC asm checks. Neither check
does anything and the XLC compiler supports GCC ASM.

always re-initialize vmhole *before* mca_base_component_var_register()
otherwise the vmhole gets NULL'ified if orte is initialized a second time.
that typically occurs when Open MPI is configure'd with --disable-dlopen
and the app does MPI_T_init_thread(); MPI_T_finalize(); MPI_T_init_thread();

It turns out that the approach of having the HNP do the
fork/exec of MPI ranks on the head node in a SLURM environment
introduces problems when users/sysadmins want to use the SLURM
scancl tool or sbatch --signal option to signal a job.
This commit disables use of the HNP fork/exec procedure when
a job is launched into a SLURM controlled allocation.
