I see, thanks.  Very likely an oversight of mine, patch to be attached.

If you still have the build tree around, would you mind checking that it fixes
the problem?  For example, apply it to the tree, run 'make quickstrap' from
within the gcc/ subdir of the build dir and then 'make all-target-libjava' from
the build dir itself.
