IMHO we should defer applying this by a few months, given that GDB support
is only being added these days and -gdwarf-4 is now the default.
Applying it in August/September when there is already GDB version with
the support would be better.

Shouldn't this be < 4?  I think DWARF 3 doesn't have constant class
DW_AT_high_pc.
