Bug#859960: gcj-jdk: dh_javadoc: please add -notimestamp to invocation

[Chris West <solo-debianbugs@goeswhere.com>]

Package: gcj-jdk
Version: 4:6.3.0-4
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps toolchain
Priority: wishlist

By default, the javadoc(1) command adds timestamps to the generated
HTML. This prevents any build package from being reproducible. This
isn't useful in a Debian packaging context, so the solution is to
simply omit the timestamp from the generated html. The javadoc command
has been altered to support this, using the -notimestamp option.

Please change the dh_javadoc command to always exec javadoc with
-notimestmap.

This will cause packages like https://tests.reproducible-builds.org/jaminid
to build reproducibly.

Thanks!
