Bug#1146516: rxtx FTCBFS: fails running host's javac

[Helmut Grohne]

Source: rxtx
Version: 2.2.0+dfsg-3.1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

rxtx fails to cross build from source, because it fails running
/usr/bin/javac, which happens to be a host architecture executable.
Usually, when building Java packages, one needs a native development kit
and sometimes also the host's runtime libraries. I tried building with
just the native development kit and that happens to just work. Please
consider applying the attached patch.
