Odd...  Must be something else.  I added a new target to the main
Makefile:

echo:
	@echo "CFLAGS='$(CFLAGS)'"

Shows up I'm using '-O0':

CFLAGS=' -Wall -Wshadow -Wwrite-strings -Wundef -Wstrict-prototypes
-Wunused -Wunused-parameter -Wunused-function -Wunused-value
-Wmissing-prototypes -Wmissing-declarations -Wdeclaration-after-statement
-Wbad-function-cast -Wold-style-definition -fno-builtin-strlen
-finline-limit=0 -fomit-frame-pointer -ffunction-sections -fdata-sections
-fno-guess-branch-probability -funsigned-char -static-libgcc
-falign-functions=1 -falign-jumps=1 -falign-labels=1 -falign-loops=1 -g
-O0  -march=i386 -mpreferred-stack-boundary=2'

And that's because I build with CONFIG_DEBUG_PESSIMIZE=y in my .config.
Doing:

	$ make CONFIG_DEBUG_PESSIMIZE= bloatcheck

shows "savings" in the 300K range:
