Does that mean you can't reasonably use 11 on most distributions without
explicitly using -gdwarf-4?  The release notes suggested to me it would still
work, just not with full functionality somehow, and there is some adjustment
for the binutils version.  Is there some way to configure it to default to
DWARF 4 other than, I guess, adding specs to treat -g as -gdwarf-4?
