I disagree with this change.  Debug builds are very useful to have in
production, and you don't want to be running -O0 there.  I have found
that you can use a src/Makefile.custom like this for those times when you
want to debug stuff in a particular set of files:

CFLAGS := $(patsubst -O2,-O0,$(CFLAGS))

Then you remove the .o files that you want to debug, and rerun make.
This places the burden on the developer wanting to mess with random code
changes.  Of course, this means that production builds are not as
debuggable, but IME it's much less of a problem there.
