Not having this check was causing distcheck errors on the OMPI
tarball-build machine because it's still a 32-bit-default machine, so
the evutil.c code was failing some #if conditionals (since it didn't
think it had strtoll available).

Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options.
Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions.
