GCC 4.8.x: default to DWARF2 instead of DWARF4
1) Dwarf4 debug info is 3-4 times bigger than Dwarf2,
2) it only helps C++11 debugging,
3) to be able to debug such programs, one needs bleeding edge tools like gdb 7.6.
with older versions, there is no error message at all, only a failure to show
the right source files (only _start/.init asm is shown).
