README-builds.html

* Florian Weimer:

It turns out that this happens when I specify build/linux-amd64 instead
of build/linux-amd64/j2sdk-image from an OpenJDK 7 build as ALT_BOOTDIR.
If I use the j2sdk-image directory, the build proceeds.

Once I feel a bit more confident about the build results, I'm going to
propose suitable changes to README-builds.html.
