IMPALA-10046: Switch backend to compile with DWARF 4 debug info
Currently, Impala compiles with -gdwarf-2 to use DWARF 2 debug
information. DWARF 4 provides better C++ language support and
better compression (reducing binary sizes), but it requires
GDB 7.0 or above. All of the Linux distributions that Impala
supports now have GDB 7.0 or above. This switches to using DWARF 4.
Binary sizes are reduced somewhat:
| DWARF 2 size | DWARF 4 size
impalad DEBUG | 573321352 | 519329200
impalad RELEASE | 713582048 | 693286800
This is also true for all unit tests. This has no impact on the
stripped binary sizes.
Testing:
- Ran core job
- Created a minidump and resolved it via the usual method
- Attached to impalad with gdb, set breakpoints, took backtraces, etc.
