You are looking for c/src/lib/libbsp/sparc/leon3/make/custom/*cfg

If you check these file in 4.11.x, I think they will have those arguments
added.

You will also have to modify the linkcmds to account for wildcards needed
in section names. Each function/data item will go in a unique section
and you need wildcards. Again the 4.11.x linker script for the leon3
should be a guide.

Is this is Gaisler release?
