This won't work.  You need to do: make DEBUG_FLAGS="-g3 -ggdb -O0"

The important part is not using -D.  make.conf variables aren't exported
into the compiler environment (I'm not phrasing this eloquently because
I don't know how to describe it).  The rest of the gcc arguments I
provided are highly recommended (especially -O0, otherwise you probably
won't get access to any variable data).

I can confirm this works, by the way.  Look closely at the cc line (past
the initial -O2 -pipe -march=nocona).

cc -O2 -pipe -march=nocona -I.  -I/usr/src/usr.bin/csup/../../contrib/csup -DHAVE_FFLAGS -DNDEBUG -ggdb -g3 -O0 -std=gnu99 -fstack-protector -Wsystem-headers -Werror -Wno-pointer-sign -c /usr/src/usr.bin/csup/../../contrib/csup/updater.c
