It seems that these flags apply to the target processor, not SDCC itself.

If you're trying to compile SDCC, "./configure --help" will give you help on
configuration options. This will apply to SDCC for your development platform
only; not the target processor for which SDCC compiles programs for.
If you want to compile a program for a target microprocessor, you'll have to
make your own Makefile. "./configure" won't apply, here.
Here's an example (attachment) for a particular Z80 target.
Your specific flags (--model-large --stack-auto) should go in the MFLAGS
variable.
Good luck!
