gcj-native-helper 2:1.8-57ubuntu1 (i386 binary) in ubuntu yakkety

 This dependency package points to the build dependencies used to build
 gcj native packages.
 .
 Unlike default-jdk-builddep, this package only provides the
 helpers to compile jar/class files into native code and not
 a Java Development Kit (JDK). You do not need this package
 unless you are compiling jar/class files to native code.
