* configure.in: check whether backtrace(3) works well or not.

* vm_dump.c: set HAVE_BACKTRACE 0 if BROKEN_BACKTRACE.

* vm_dump: FreeBSD ports' libexecinfo's backtrace(3) can't trace
  beyond signal trampoline, and as described in r38342 it can't
  trace on -O because it see stack frame pointers.
  libunwind unw_backtrace see dwarf information in the binary
  and it works with -O (without frame pointers).

* configure.in: remove r38342's hack and check libunwind.
