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:

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.

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.

This commit fixes a compile/link issue caused by vader. The vader btl
was using OPAL_THREAD_ADD64 to increment a counter which may not be
available on 32-bit systems. Changed to use OPAL_THREAD_ADD_SIZE_T
which will be 64-bit or 32-bit depending on the system.

ebx can not be clobbered when using -fPIC so save and restore the
register instead of allowing it to be clobbered.
