You don't really need a new option to use specific CFLAGS (or others). 
Just pass them to the configure script (or make) directly:

./configure CFLAGS='...'

or

make CFLAGS='...'

I always build with -Wall -Wextra -pedantic using the first variant 
(which means I only have to set the right options once).
