Bug#951573: javatools: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
jssc could not be built reproducibly. I eventually tracked this down
and I think this is very similar to a similar, older issue detailed
here:

  https://bugs.debian.org/926542
  
... as somehow debhelper itself was parsing this strangely and ending
up printing warnings such as:

   -s/--same-arch is deprecated; please use -a/--arch instead

If I applied the following patch to src:jssc then the build became
reproducible:

-	jh_build -o "-source 1.6 -target 1.6 -encoding UTF-8" --javadoc-opts="-source 1.6 -encoding UTF-8"
+	jh_build --javacopts "-source 1.6 -target 1.6 -encoding UTF-8" --javadoc-opts="-source 1.6 -encoding UTF-8"

… but that seems a bit silly.

Patch for javastools attached that removes the "-o" option, but this
might not be the best idea (ie. one should likely deprecate it first,
such as how the -N short arg was also deprecated (see the top of the
jh_build file).
