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

175 # versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
176 # versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
177 # in options via environment variables, use of distinct variables
178 # prevents strange behaviours. For example, in a BUILD_FLAVOR !=
179 # product build, the FULL_DEBUG_SYMBOLS environment variable will be
180 # 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If
181 # the same variable name is used, then different values can be picked
182 # up by different parts of the build. Just to be clear, we only need
183 # two variable names because the incoming option value can be
184 # overridden in some situations, e.g., a BUILD_FLAVOR != product
185 # build.

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