[LEDE-DEV] How to build kernel module with debugging symbols?

I am trying to debug a crash in my ath10k-ct kernel driver.
I can only reproduce this on LEDE, so my normal debug tricks are not working.
How can I get LEDE to build the module with symbols so that LEDE's gdb can open it?
I verified that '-g' is being passed when compiling the module, and it does not appear
to be stripped, but symbols are not found:
