Bug#460168: lintian: ant needed in clean target

[Cyril Brulebois <cyril.brulebois@enst-bretagne.fr>]

Package: lintian
Version: 1.23.42
Severity: minor

Hi,

similarly to #457501, I noticed the following for ant:
| I: sunflow source: build-depends-without-arch-dep ant

But ant is in fact needed in the clean target, at least when used
through cdbs's ant.mk: (an equivalent to “make clean”, roughly)
| dh_clean
| cd . && /usr/lib/jvm/java-gcj/bin/java -classpath /usr/share/ant/lib/ant.jar:/usr/share/ant/lib/ant-launcher.jar:/usr/share/java/janino.jar:/usr/lib/jvm/java-gcj/lib/tools.jar  -Dant.home=/usr/share/ant org.apache.tools.ant.Main -Dcompile.debug=true -Dcompile.optimize=true     clean
| Buildfile: build.xml
| 
| init:
| 
| clean:
|    [delete] Deleting directory /home/kibi/sunflow.git/build
|    [delete] Deleting directory /home/kibi/sunflow.git/release
| 
| BUILD SUCCESSFUL
| Total time: 0 seconds

I guess that it might be a bit hard to detect because of its being java,
but, at first glance, trying to detect “/usr/share/ant/lib/ant.jar”
should do the trick.

The sunflow package currently in unstable and testing exhibits this
minor issue.

Thanks again. Cheers,
