* addr2line.c: added to show source filename and line number of

  functions in backtrace. [ruby-dev:42625]
  a patch from shinichiro.h <shinichiro.hamaji AT gmail.com>

* addr2line.h: ditto.

* common.mk: add addr2line.$(OBJEXT).

* configure.in: check dl_iterate_phdr.

* vm_dump.c (rb_vm_bugreport): use rb_dump_backtrace_with_lines in
  addr2line.c when the binary is ELF.
