I have poudriere-devel, and was thinking of doing it like so:

poudriere bulk -j 132Ramd64 -O sccache -f portslist.txt -i
(finishes bulk build, go into interactive mode)
cd /usr/ports/www/apache24
make -DBATCH -DDEBUG && make

but not sure here how I'd modify CFLAGS for -O0

There's no DEBUG in the options for this port
