You'd lose `-O2' compiler-specific optimization. If you want to retain
it use DEBUG_FLAGS, e.g.
DEBUG_FLAGS = -ggdb
CFLAGS += ${DEBUG_FLAGS}
Ports that build using bsdmake don't really need the second line as well
as buildworld.

Besides symbols some ports enable compile-time debugging and disable
optimization using WITH_DEBUG ifdef that may impact performance.
