I gave it my best shot, but my build is still unhappy.
I set:
KLIBCREQFLAGS     :=  $(call cc-option, -fno-stack-protector, )
in scripts/Kbuild.klibc.

KLIBCOPTFLAGS     = -march=i386 -Os -g -fomit-frame-pointer
$(gcc_align_option) $(call cc-option, -fno-stack-protector, )
in usr/klibc/arch/i386/MCONFIG

CFLAGS          := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \
                   $(call cc-option, -fno-stack-protector, ) -fno-common
in Makefile.

Trying to compile, I get:

include/asm/system.h: In function '__set_64bit_var':
include/asm/system.h:209: warning: dereferencing type-punned pointer
