Latest Espruino build for Esp8266

@tve, I would like to compile on my own VM.
There was something about using a different SDK, but I cannot find it anymore.
Are these commands still correct ?

git clone hhttps://github.com/tve/Espruino.git
curl -Ls http://s3.voneicken.com/xtensa-lx106-elf­.tgx | tar Jxf -
curl -Ls http://s3.voneicken.com/esp_iot_sdk_v1.5­.0.tgx | tar Jxf -
cd Espruino
