PS4, Line 543: CFLAGS_common += -g

`gcc -O2 -g -o myprogram mysource.c`
here, `O2` and `-g` flags are applied to the mysource.c file.
If we place `-g` before lake this:
`gcc -g -O2 -o myprogram mysource.c`, the `-O2` flag would override the `-g` flag for the mysource.c file, and debugging information would not be generated.

note: I'm thinking about using something like "if debug use -g flag"...
