Given what Jakub is saying, i.e. it was previously impossible to get

It isn't impossible to get it, -gdwarf-2 works, it is just not a very good
choice (at least unless one knows some debug info consumer is not DWARF3 or
later ready).
Though, even gcc -gdwarf-2 will use many extensions from DWARF3 and later,
as long as there is no way to describe stuff in DWARF2.  -gstrict-dwarf
option requests that no DWARF extensions are used.
