Hmm.  Yes, that could work.  We'd still be changing the ABI, since
the original source "bsr foo" would really mean "bsr foo+skip ldgp".
But perhaps one that wouldn't matter for all practical purposes.

This would need to be done with a new relocation type so that old
linkers that didn't handle this sort of thing choke, but that's not
a big deal.

If I find the time I may give it a shot and see what sort of 
effect it has on typical code.
