That was a little cryptic. What's happening here is that configure is
grubbing a value for CFLAGS out of the Makefile if CFLAGS wasn't set in
the environment, but it's before the host and target fragments have been
pasted in. Later, configure cleverly goes through the Makefile, after the
fragments have been pasted in, and substitutes its own value for CFLAGS...
Yuck.
