On Debian (and probably other), if I execute:

(echo $MACHTYPE gives: i486-pc-linux-gnu)

If I create i486-pc-linux-gnu-ar pointing to ar in /usr/bin:
# ln -vs /usr/bin/ar /usr/bin/i486-pc-linux-gnu-ar
`/usr/bin/i486-pc-linux-gnu-ar' -> `/usr/bin/ar'

I just need todo:
cd /home/etienne/tmp/gcc-build/gcc
gcc-cross -dumpspecs > tmp-specs
make
cd ..
make all-gcc
make install-gcc install-binutils
and I get a working compiler.
Exactly the same 2 problems on gcc-4.3.3.
Regards,
Etienne.
