155 # versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
156 # versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
157 # in options via environment variables, use of distinct variables
158 # prevents strange behaviours. For example, in a BUILD_FLAVOR !=
159 # product build, the FULL_DEBUG_SYMBOLS environment variable will be
160 # 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If
161 # the same variable name is used, then different values can be picked
162 # up by different parts of the build. Just to be clear, we only need
163 # two variable names because the incoming option value can be
164 # overridden in some situations, e.g., a BUILD_FLAVOR != product
165 # build.

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