bitbake.conf: Use -Og in DEBUG_OPTIMIZATION
-Og is for optimized debugging experience. this makes this consistent across different compilers especially gcc and clang, -O in clang is equal to -O2 where as in gcc its similar to -O1 so it was not giving consistent debugging experience across compilers (From OE-Core rev: 16643b03227466e2c80a24c2d079fe36e89553c1) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
