  # Full Debug Symbols is supported on JDK7 or newer.

  # builds is enabled with debug info files ZIP'ed to save space. For

  # BUILD_FLAVOR != product builds, FDS is always enabled, after all a

  # debug build without debug info isn't very useful.

  # The ZIP_DEBUGINFO_FILES option only has meaning when FDS is enabled.

  #

  # If you invoke a build with FULL_DEBUG_SYMBOLS=0, then FDS will be

  # disabled for a BUILD_FLAVOR == product build.

  # versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS

  # versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass

  # in options via environment variables, use of distinct variables

  # prevents strange behaviours. For example, in a BUILD_FLAVOR !=

  # product build, the FULL_DEBUG_SYMBOLS environment variable will be

  # 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If

  # the same variable name is used, then different values can be picked

  # up by different parts of the build. Just to be clear, we only need

  # two variable names because the incoming option value can be

  # overridden in some situations, e.g., a BUILD_FLAVOR != product

  # build.

  # Due to the multiple sub-make processes that occur this logic gets

  # executed multiple times. We reduce the noise by at least checking that
