Currently, we can't call opal wrappers from modules when using the LE
ABIv2, which requires a TOC init.

What happens if we try? Build failure or run time bug?

This change uses the _GLOBAL_TOC() macro (rather than _GLOBAL) for the
opal wrappers, so that we can do non-local calls to them.

Are we doing that now, or we would like to?
