So you probably won't need SCSI or floppy drivers or any of the filesystems. 
These can be disabled by editing config/examples/cross-sparc32_config.xml. 
What kind of serial port is this, Zilog or PC (16550)?

That can be difficult to achieve, currently the full build is 150k C code + 
100k Forth. I don't know how much of the Forth is needed. Taking out 
unwanted drivers etc. could help a lot on C side, but down to 30-40k?
