[Bug libgcj/40860] [4.4/4.5 regression] regressions in libjava testsuite on arm-linux

I decided to attack things from the binutils side. The problematic binutils
change rolls two distinct changes into one (add cantunwind table entries, merge
adjacent equivalent table entries). Disabling the "merge" part eliminated the
libjava regressions in my ARM mode build:

--- binutils-2.20.51/bfd/elf32-arm.c.~1~
+++ binutils-2.20.51/bfd/elf32-arm.c

                                     DELETE_EXIDX_ENTRY, NULL, j / 8);

              deleted_exidx_bytes += 8;
+#endif
            }

          last_unwind_type = unwind_type;

I'll keep experimenting.
