In addition to specifying CFLAGS at configure time, you can also give an
override at compile time, like so
make CFLAGS="-ggdb -O0"
Of course, this will only affect those files that get recompiled but
with `make clean` (or selective removal of *.la and *.lo files) that
should be easy to control.
I use this approach quite a bit to avoid a time consuming configure step
and only override stuff for those files I want to focus on.
Hope this helps,
