Build changes look good.

I'm just a bit curious about the added, empty, `src/java.desktop/share/native/libharfbuzz/abc.txt`...

If it really is in upstream source, I'm not saying you should remove it. It just looks very odd. It's not a merge artifact?

(I could not even add review comments to an empty file in github!  ��)
