Have a look here for an example of using a custom crt.s:

Hello Adam,
I think you're supposed to take our crt.s and modifiy it to your needs
with the missing jumps.
https://sourceforge.net/p/sdcc/code/HEAD/tree/trunk/sdcc/device/lib/z80/crt0.s
Assemble it and then link it with the rest of your application.
