Patches were posted to make it work in C but didn't make it apparently.

Confirmed: flag_trampolines matters only for calls with the ECF_BY_DESCRIPTOR bit set or CALL_EXPR_BY_DESCRIPTOR being true. Other than from the Ada backend, such calls are generated only from gimple nodes with subcode bit GF_CALL_BY_DESCRIPTOR set. GF_CALL_BY_DESCRIPTOR gets set through gimple_call_set_by_descriptor with argument true, and such calls exist only as consequence of tree nodes with CALL_EXPR_BY_DESCRIPTOR being true.
