161 # versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
162 # versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
163 # in options via environment variables, use of distinct variables
164 # prevents strange behaviours. For example, in a BUILD_FLAVOR !=
165 # product build, the FULL_DEBUG_SYMBOLS environment variable will be
166 # 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If
167 # the same variable name is used, then different values can be picked
168 # up by different parts of the build. Just to be clear, we only need
169 # two variable names because the incoming option value can be
170 # overridden in some situations, e.g., a BUILD_FLAVOR != product
171 # build.

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