You don't need ecj1 to build libgcj.  You only need ecj1 if you are
going to recompile any of libgcj from source.  That will only happen
if you need to change any of the gcj java sources.

ecj1 _only_ gets called at build time if you use
--enable-maintainer-mode.  You don't need to do that to build a
cross-compiler.
