WRAPPER_EXTRA flags are checked *before* the POST_CONFIG macro is
invoked. So set them in the main CONFIG macro.

This commit changes the asm configure logic to fall back on inline asm
atomics on systems that 1) have __sync atomics, 2) do not have 64-bit
__sync atomics, and 3) support 64-bit asm.

Thanks Paul Hargrove for the report and the patch
Intel TrueScale and Intel OmniPath, and detect a link in ACTIVE state.
This fix addresses the scenario reported in the below OMPI users email,
including formerly named Qlogic IB, now Intel True scale. Given the
nature of the PSM/PSM2 mtls this fix applies to OmniPath:

This commit adds an additional check for 64-bit atomic support for __sync
builtins. If 64-bit support is not available the opal_atomic_*_64 atomics
are disabled.

xlc 13.1.0 crashes because of our may_alias attributes in nolibxml.c
on Power7. libxml.c and nolibxml.c are the only may_alias users for now,
so change our configure check to match the actual code using it.
Thanks to Paul Hargrove for reporting and debugging the issue,
and providing the patch.

(cherry picked from open-mpi/hwloc@0ab7af5e90)
Per discussion on the mailing list and with IBM, remove the AIX timer
code (since AIX is no longer supported).

MPIR-1.0 specifies that the following symbols are only relevant in the
starter process:
- MPIR_Breakpoint
- MPIR_being_debugged
- MPIR_debug_state
- MPIR_debug_abort_string
I.e., the code filling in values in these various symbols was useless
/ never used.
MPIR-1.1 will define that MPIR_being_debugged *is* relevant in MPI
processes. That symbol is currently defined in libopen-rte (which is
currently causing a duplicate symbol error for static builds -- this
commit fixes that error), and is therefore still available for MPI
processes.

MPI-3.1 says that even if no info keys are set on the file, we need to
return a new, empty info.
Thanks to Lisandro Dalcin for identifying the issue.

This commit disables the linux patcher component due to a limitation
in loader patching. While this component is effective in patching
calls made within Open MPI and by the application it fails to hook
calls made within glibc. This means the munmap call made by free is
not correctly hooked. Until this problem can be resolved this
component will remain disabled. If it can't be resolved this component
should probably be removed.

The table of contents (TOC) code only appears to only apply to
ppc64. The code was incorrectly assuming the existence of the TOC on
ppc32. This commit updates the necessary code to only apply to ppc64.
