Which port are you working on? I don't see how ELF would make a
difference here (but if you want to see for yourself, have a look at one
of the ports that do support ELF output (hc08, s08, stm8)).
Typical SDCC targets are small systems with RAM and ROM/Flash, and SDCC
needs to take care of initializing data on startup.
