It's odd.  If you have gcj installed on your host machine, you should
have i686-pc-linux-gnu-gcj on your path somewhere.  On my x86_64 box
I have install/bin/x86_64-unknown-linux-gnu-gcj.  Configure is using
i686-pc-linux-gnu-gcj because it detected it, so I can't see why it
isn't found at build time.

If you could tell us the configure options you used and the output of
configure, that would help.
