configury: new OPAL_SET_LIB_PREFIX/ORTE_SET_LIB_PREFIX macros
These two macros set the prefix for the OPAL and ORTE libraries,
respectively. Specifically, the OPAL library will be named
libPREFIXopen-pal.la and the ORTE library will be named
libPREFIXopen-rte.la.
These macros must be called, even if the prefix argument is empty.
The intent is that Open MPI will call these macros with an empty
prefix, but other projects (such as ORCM) will call these macros with
a non-empty prefix. For example, ORCM libraries can be named
liborcm-open-pal.la and liborcm-open-rte.la.
This scheme is necessary to allow running Open MPI applications under
systems that use their own versions of ORTE and OPAL. For example,
when running MPI applications under ORTE, if the ORTE and OPAL
libraries between OMPI and ORCM are not identical (which, because they
are released at different times, are likely to be different), we need
to ensure that the OMPI applications link against their ORTE and OPAL
libraries, but the ORCM executables link against their ORTE and OPAL
libraries.

Put back the static-library-detection stuff from r27668, with some
additional functionality. Rationale (refs trac:3422):
* Normal MPI applications only ever use the MPI API. Hence, -lmpi is
sufficient (they'll never directly call ORTE or OPAL
functions). This is arguably the most common case.
* That being said, we do have some test programs (e.g., those in
orte/test/mpi) that call MPI functions but also call ORTE/OPAL
functions. I've also written the occasional MPI test program that
calls opal_output, for example (there even might be a few tests in
the IBM test suite that directly call ORTE/OPAL functions).
* Even though this is not a common case, these applications should
also compile/link with mpicc.
* So we should add a --openmpi:linkall option that will also link
in whatever is necessary to call ORTE/OPAL functions
* Yes, we could hard-code "-lopen-rte -lopen-pal" in Makefiles, but
we do reserve the right to change those library names and/or add
others someday, so it's better to abstract out the names and let
the wrapper supply whatever is necessary.
* ORTE programs, however, are different. They almost always call OPAL
functions (e.g., if they want to send a message, they must use the
OPAL DSS). As such, it seems like the ORTE programs should always
link in OPAL.
Therefore:
* Add undocumented --openmpi:linkall flag to the wrapper compilers.
See the comment in opal_wrapper.c for an explanation of what it
does. This flag is only intended for Open MPI developers -- not
end users. That's why it's undocumented.
* Update orte/test/mpi/Makefile.am to add --openmpi:linkall
* Make ortecc/ortec++'s wrapper data text files always explicitly
link in libopen-pal
