The rtl emitting code might do it, or jump.c (look for gen_return).
I think the easiest way to fix this is just to change the predicate
of the "return" instruction in the *.md file to always return false
while a naked function is compiled.

That will force rtl generation to generate jumps to the end of the function
instead of returns, and inhibit any optimizations that generate returns.
