I've no idea what's going on there: modulo pathname and target triplet
differences, I have exactly the same gcj command line to link
jv-convert.  Could you please manually invoke that command with -v
added, so I can see how exactly collect2 resp. ld is called?

What I do see is that if you add some -W option to ld, you get exactly
the message you observe.  E.g.

ld -G 8 -O3 -S -call_shared -o .libs/jv-convert /usr/lib/cmplrs/cc/crt0.o
-L.libs -L. -L../../gcc -L/usr/lib/cmplrs/cc gnu.gcj.convert.Convertmain.o
./.libs/libgcj.so -lpthread -lrt -rpath /vol/gcc/lib -lgcc_s -lgcc -lgcj -lm
-liconv -lpthread -lrt -lgcc_s -lgcc -lc -lgcc_s -lgcc -Wno-unused
ld:
Invalid flag usage: Wno-unused, -Wx,-option must appear after -_SYSTYPE_SVR4 
ld: Usage: ld [options] file [...]

Do you happen to have some environment variable set to -W<something>?
Though I have found no hint that ld would check for this, it's a
possibility.
