I tried adding "-32" like this:

Still generates 64-bit object files:

root at deb4g:~/fpc/fpc-3.0.0+dfsg# file /root/fpc/fpc-3.0.0+dfsg/fpcsrc/rtl/units/sparc-linux/strings.o
/root/fpc/fpc-3.0.0+dfsg/fpcsrc/rtl/units/sparc-linux/strings.o: ELF 64-bit MSB relocatable, SPARC V9, relaxed memory ordering, version 1 (SYSV), not stripped
root at deb4g:~/fpc/fpc-3.0.0+dfsg#

Any idea?

Adrian
