Yes, because there is no default linker script, gold does not support
INSERT BEFORE or INSERT AFTER.

Gold also does not support SORT_NONE. Try removing that.

Ideally, you should try to find a way to link your code without a
custom linker script at all. If you're using CO_BUFFER_BEGIN and
CO_BUFFER_END as bracketing sections to provide a start and stop
symbol, you can try using the linker-generated __start_COBUFFER and
__stop_COBUFFER symbols instead. Likewise for the COHOOK section.
