autoconf sets this, not automake.

At configure time:
CFLAGS=-g ./configure ...
(with autoconf 2.5x you can use `./configure CFLAGS=-g ...', which is
easier to remember)
At build time:
Macros like CFLAGS, CXXFLAGS, etc, are there for the user to use.
Unfortunately there still isn't a nice document explaining what
features automake provides to the person building the package :-(
