'-g3 -O0' I had to pass it as CFLAGS='-g3 oO0'.

If you wish to use non-default GCC flags when compiling the stage2 and
stage3 compilers, set BOOT_CFLAGS on the command line when doing
`make'.
Thanks Jonathan.
I also noticed the same info here:

Well, I think what I did that; however, when I got into gdb, I got this:

What am I doing wrong now? Should I do `make install` also?
OOPS, tried that and didn't help.
Please help!
