I ran into this problem a while ago, and after discussion on the
mailing list, added a -gdwarf option to emit DWARF with the default
version (http://gcc.gnu.org/ml/gcc-patches/2013-04/msg00592.html). Might
be better than hardcoding dwarf-2 IMO.

Yeah, definitely.

	Jakub

Here is the patch, amended to use -gdwarf.
Tested on i686-pc-linux-gnu.

Ok to apply?
