I found this on gcc-patches from 2011-11, maybe it does solve something also for ARM?
"[patch, ia64, libgcc] Patch to fix libunwind build on IA64"
http://gcc.gnu.org/ml/gcc-patches/2011-11/msg01926.html
The patch is basically modding Makefile.in as:
# Build LIBUNWIND.
-c_flags := -fexceptions
+c_flags := -fno-exceptions
I though think my patch proposal could be interesting though to be able to control it from configure.
