You're right in that you didn't add this, just moved it to a different
file.  I found, when attempting to get IcedTea7 to build b78, that
we've been patching it out since 2008:

2008-06-29  Matthias Klose  <doko at ubuntu.com>

        * patches/icedtea-jdk-docs-target.patch: New.

I think http://cr.openjdk.java.net/~andrew/build/webrev.02/tl.patch
gives an acceptable compromise and shouldn't break Sun's proprietary
builds.  Can I have a bug ID to push this?
