For now, you can include
void _sdcc_gsinit_startup(void)
{
__asm pagesel _main __endasm;
__asm goto _main __endasm;
}
into your project sources and thus prevent the linker from including
sdcc's library implementation of globals and statics initialization.
If you add the function to the file that also contains your main(),
you can even leave out the pagesel, which shortens the function code
further from 6 to 2 bytes (3 => 1 instruction).
Adding a command line option (say "sdcc --no-gsinit-startup") could
save additional 2 bytes and would be more convenient ...
