First, NOGDB=1 is related to compilation of the IDE. You do not need to
care about that because you primarily need to compile the compiler with
support for debugging (you can still use the previously available IDE or
GDB as before, no need to use your new build for that). Second, you
apparently didn't add the options suggested by Jonas to your command line:
sudo make clean all "OPT=-O- -gl" NOGDB=1
(and possibly even extending it to "OPT=-O- -gl -Xs-")

I cannot answer this one for Mac OS X.
