Using
ARCH=$TARGET_ARCH make $1 V=1
in the build script (CFLAGS set in the environment) I get
 
/home/davide/geexbox/dev/geexbox-davide/build.i386.eglibc/toolchain/bin/i586-geexbox-linux-gnu-gcc
-Wp,-MD,shell/.ash.o.d    -Iinclude -Ilibbb  -include include/autoconf.h
-D_GNU_SOURCE -DNDEBUG -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -D"BB_VER=KBUILD_STR(1.15.2)" -DBB_BT=AUTOCONF_TIMESTAMP
-Os -Wall -pipe -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -mtune=generic
-march=i586 -g3          -Wold-style-definition        -std=gnu99    
-D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(ash)" 
-D"KBUILD_MODNAME=KBUILD_STR(ash)" -c -o shell/ash.o shell/ash.c

Forcing CFLAGS with -funsigned-char in the environment
ARCH=$TARGET_ARCH CFLAGS="$CFLAGS -funsigned-char" make $1 V=1

Passing CFLAGS as make parameter
