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 sti=
ll
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?=
