   # 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.
   #
   # 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
   # BUILD_FLAVOR has been set.
