Some debuggers do not cope with the new DWARF3/4 debug format introduced

This patch should be committed to GCC 4.8 and 4.9.
I am opposed to this patch, because
* GNU software should not care about the limitations of commerical stuff and
should only care about gdb.
Actually GCC cares about commercial stuff, e.g. the VxWorks and Darwin ports
use exactly the same mechanism.
The SPARC version of GDB seems to have problems here also:

* We should stay with the GCC's defaults and not diverge from these.
In general this is true.
* Users, who are facing issues with commerical stuff can always manually pass
appropriate options to CC if they need it.
This approach is not possible for the multilibs.
