Try building busybox instead; it comes with ash.

Here's how I build busybox:
I have an outer Makefile that unpacks, configures, and builds it.

NAME=busybox-0.60.2
DEST=/home/dank/ixia/Source/linux/port/ppc405/staging/fsimg/bin
MKVARS=CROSS=/opt/hardhat/devkit/ppc/405/bin/ppc_405-

REFIX=/home/dank/ixia/Source/linux/port/ppc405/staging/fsimg

PROGS_BIN:= $(DEST)/busybox
/home/dank/ixia/Source/linux/port/ppc405/staging/fsimg/sbin/init
PROGS   := ppc405/busybox

all: $(PROGS)

install: $(PROGS_BIN)

/home/dank/ixia/Source/linux/port/ppc405/staging/fsimg/sbin/init: .FORCE
        -rm -f
/home/dank/ixia/Source/linux/port/ppc405/staging/fsimg/sbin/init
        cp

# dummy rule to force us always to overwrite init
.FORCE:

uninstall:
        rm -f $(PROGS_BIN)
        # remove old symlinks
        find /home/dank/ixia/Source/linux/port/ppc405/staging/fsimg
-lname '*busybox' -exec /bin/rm '{}' ';'

clean:
        rm -rf ppc405 $(NAME)

$(NAME)/Config.h: /home/dank/ixia_tarballs/$(NAME).tar.gz Config.h
        tar -xzvf  /home/dank/ixia_tarballs/$(NAME).tar.gz
        cp Config.h $(NAME)/Config.h
        patch -p0 < path_max.patch

$(PROGS): $(NAME)/Config.h
        test -d ppc405 || mkdir ppc405
        make $(MKVARS) -C ppc405 -f ../$(NAME)/Makefile

ppc405/busybox.links:
        ln -s ../$(NAME)/busybox.links ppc405/busybox.links

$(DEST)/busybox: ppc405/busybox ppc405/busybox.links
        if test -f $@ ; then chmod +w $@ ; fi
        cp $< $@
        make $(MKVARS) -C ppc405 -f ../$(NAME)/Makefile install

(the above has spaces instead of tabs, so you'd have to 'unexpand' it 
to use it as a Makefile)

See attachments for other files (and a tabified Makefile).
