right, i've just managed to build static binutils for x86-cross-sparc

roman@athlon1000:~/crosstool/sparc-unknown/bin> ls
sparc-unknown-linux-gnu-addr2line  sparc-unknown-linux-gnu-ld 
sparc-unknown-linux-gnu-ranlib   sparc-unknown-linux-gnu-strip
sparc-unknown-linux-gnu-ar         sparc-unknown-linux-gnu-nm 
sparc-unknown-linux-gnu-readelf
sparc-unknown-linux-gnu-as         sparc-unknown-linux-gnu-objcopy 
sparc-unknown-linux-gnu-size
sparc-unknown-linux-gnu-c++filt    sparc-unknown-linux-gnu-objdump 
sparc-unknown-linux-gnu-strings

roman@athlon1000:~/crosstool/sparc-unknown/bin> file *as
sparc-unknown-linux-gnu-as: ELF 32-bit LSB executable, Intel 80386, 
version 1 (SYSV), statically linked, not stripped

roman@athlon1000:~/crosstool/sparc-unknown/bin> ldd *as
        not a dynamic executable

roman@athlon1000:~/crosstool/sparc-unknown/bin>

the key is to
run "configure" with --disable-nls option
run "make configure-host"
run "make configure-target"
run "make LDFLAGS=-all-static"
run "make install"

Note: you need to change line "make LDFLAGS=-all-static all" to "make 
LDFLAGS=-all-static" otherwise build will fail
anyway below is the function for building static binutils from my scripts

mkbinutils() {

echo "Unpacking binutils sources" \
&& cd $BUILDDIR && unpacksrc $BINUTILS \
&& echo "Patching binutils source tree" \
&& patchsrc $BINUTILS \
&& mkdir -p $BUILDDIR/binutils-build \
&& cd $BUILDDIR/binutils-build \
&&
if test '!' -f Makefile
then
    $BUILDDIR/$BINUTILS/configure --target=$MTARGET 
--prefix=$INSTALLDIR --disable-nls
fi \
&& make configure-host \
&& make configure-target \
&& make LDFLAGS="-all-static" \
&& make install \
&& cd .. \
&& rm -rf $BUILDDIR/binutils* \
&& if test ! -x $INSTALLDIR/bin/$MTARGET-ld
then
    return 1
fi
