Odd... why is the linker complaining? Also I'm surprised that it's
symlinked to libSystem. Try
file /usr/lib/libgcc_s.1.dylib
to see the architectures included, and edit Makefile to add -v to
FBFLAGS, and see what it passes to as.
A desperate possibility for fix would be adding '-Wl -lgcc_s.10.4' to FBFLAGS

It might also help to see what gcc passes to ld:
echo "int main() {return 0;}" > /tmp/test.c && gcc -m32 /temp/test.c -v
