  # Full Debug Symbols is supported on JDK7 or newer.
  # The Full Debug Symbols (FDS) default for BUILD_FLAVOR == product
  # 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.
  #
  # Note: Use of a different variable name for the FDS override option
  # 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
