Yep.  You'll have to add an ENCODE_SECTION_INFO hook that sets
SYMBOL_REF_FLAG, and we'll have to modify sjlj_emit_function_enter
to gen up a fake VAR_DECL to pass to ENCODE_SECTION_INFO.

I could give it a shot later this week, but I don't have openbsd
installed anywhere to test it.

I suspect that profile directed feedback is broken similarly.
