That's what I usually do. Setting CFLAGS really means "I know this
better than configure", and then configure obeys without questioning.
One could have some user option EXTRA_CFLAGS or the like but I'm not
sure that's really worth the effort.

It might also work to set CC='gcc -g', but I haven't tested.

As for -g, I'm not sure why it is disabled by default in gmp builds. I
think GNU standard is to enable -g by default when building with gcc
(which has always had reasonable support for generating useful debug
info also when optimizing).
