It's to cater to a common usage, where one does
"configure CC='cc -m32'; [edit]; make CFLAGS=-g".
"configure" may decide to use "-g -O2", but you may find it easier
to compile with plain -g than with -g -O2, because it's easier to debug
code that isn't optimized.
If instead you use "configure CC=cc CFLAGS=-m32", it's more of
a pain: "configure" won't set all the CFLAGS for you, and when
you run "make" yourself you need to say "make CFLAGS='-m32 -g'".
