libjava needs a reliable backtrace () function, so whether or not
the glibc backtrace () uses DWARF-2 CFI can make a difference.

In any case, the s390 situation is probably not immediately applicable
to other archs, since we actually *disabled* the traditional stack
back-chains with gcc 3.4, so that old backtrace () routines definitely
cannot work any longer.
