Until now, the ESP8266 target used a non-tagged git hash revision of the RTOS SDK (from Oct 2017). Moreover, the compiler was also a custom-built gcc. This commit sets the RTOS SDK version to v2.1.0, released Oct 2018, which is the latest old-style SDK for ESP. The commit also changes the used gcc to an Espressif-provided pre-built toolchain, which is tagged for the (latest) v3.0.1 SDK release. (The SDK bump is not to the latest SDK version because the new v3.x line of the SDK is "ESP-IDF style", which is incompatible with the current target code base. On the other hand, the toolchain comes from the latest SDK release because the v2.x line had no pre-built toolchain suggestions -- but it builds v2.x sources correctly.)
