./configure --with-dwarf3

Hi.

I recently built `Fedora-14` gcc SRPM on `RHEL-6.8` to have
`AddressSanitizer`. Everything works except that old gdb there doesn't
show me local variables and source listing. This can be fixed by
compiling my programs with -gdwarf-3.

Is it possible to make DWARF version 3 default, like it was in gcc 4x? I
saw the configure option '--with-dwarf2', but no equivalent '--with-dwarf3'.

Do I need version 3 at all or is version 2 also good?
