5 years ago To be clear, wolfssl does configure this way via autoconf when on an x86 target, so this should be moved to any x86 target platforms or else the library will not work due to a misconfiguration of wolfssl and libiotc. In this case, osx and linux are safe bets. freertos and zephyr are expected to target embedded platforms which are almost certainly non-x86 targets and their makefiles can configure wolfssl appropriately.
This build flag causes issues when building for non-x86 build targets. Should be removed and referenced in platform specific wolfssl build configs
