This kind of thing is OK for HEAD, but to me seems like something which is
not OK for a stable branch.

Before your change:   "cc -g" from base + gdb in base =  can debug
After your change:      "cc -g" from base + gdb in base = cannot debug

Is it possible to modify clang in base, so that
on the stable branches, "cc -g" will output dwarf-2 instead of
dwarf-4 by default?

I understand that installing gdb from ports, changing compiler flags
from -g to -gdwarf-2 in Makefiles,
or switching to compiling with gcc are all reasonable workarounds,
but this seems a bit like POLA for a stable branch.
