'''
Generate BuildConfig Java source files.

BuildConfig files are the Gradle way of configuring Java values at build time.

This is the moz.build equivalent of Gradle's `buildConfigField` (see
http://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.ProductFlavor.html#com.android.build.gradle.internal.dsl.ProductFlavor:buildConfigField(java.lang.String,%20java.lang.String,%20java.lang.String).
This mechanism will be replaced with the Gradle native version as we
transition to Gradle.
