methods (in order of precedence):
1. #pragma ident <ident string> (e.g., Intel and Sun)
1. #ident <ident string> (e.g., GCC)
1. static const char ident[] = <ident string> (all others)
By default, the ident string used is the standard Open MPI version string. Only
the following libraries will get the embedded version strings (e.g., DSOs will
not):
* libmpi.so
* libmpi_cxx.so
* libmpi_f77.so
* libopen-pal.so
* libopen-rte.so
* Added two new configure options:
* `--with-package-name="STRING"` (defaults to "Open MPI username@hostname
Distribution"). `STRING` is displayed by `ompi_info` next to the "Package"
heading.
* `--with-ident-string="STRING"` (defaults to the standard Open MPI version
string - e.g., X.Y.Zr######). `%VERSION%` will expand to the Open MPI
version string if it is supplied to this configure option.
