In particular, I was just wondering how do compile GCC with debug. Not
how to debug it. I tried CFLAGS="-g" ./configure ..., but it still
compiled with gcc -O2 -g. Anyways, if anyone knows a helpful configure
trick that will help get me ready to debug gcc, please let me know.

By default, GCC bootstraps itself, and after the first stage it always compiles itself with optimization enabled. So what you need is

./configure --enable-languages=c,c++ --disable-bootstrap
make CFLAGS=-g

(or equivalently, with CFLAGS=-g passed to configure).
