branch spurious references to __gxx_personality_v0

[Zack Weinberg]

I'm trying to merge the changes to break the libjava->libsupc++
dependency onto the 3.0 branch.  Builds fail with undefined references
to __gxx_personality_v0:

$ nm -o libgcj.a | grep __gxx
libgcj.a:natInput_EUCJIS.o:            U __gxx_personality_v0
libgcj.a:natInput_SJIS.o:              U __gxx_personality_v0
libgcj.a:natOutput_EUCJIS.o:           U __gxx_personality_v0
libgcj.a:natOutput_SJIS.o:             U __gxx_personality_v0
libgcj.a:shs.o:                        U __gxx_personality_v0
libgcj.a:natMath.o:                    U __gxx_personality_v0
libgcj.a:natPlainDatagramSocketImpl.o: U __gxx_personality_v0
libgcj.a:natPlainSocketImpl.o:         U __gxx_personality_v0
libgcj.a:natGregorianCalendar.o:       U __gxx_personality_v0

None of these files use exceptions at all, as far as I can tell.  Up
till yesterday we had the exact same problem on the trunk, but it has
now gone away.  I cannot figure out what change corrected the problem.
Any ideas?
