[Linux] cross compile tmux for Synology DS216play via DSM 6.1 Tool Chains - STMicroelectronics Monaco Linux 3.10.102 @ Ubuntu 16.04 64bit

連假最後一天跑來把玩一下 cross compiler ，想說未來應該會越來越常用 NAS 做事，覺得裡頭沒有個 tmux/screen 很煩，然而，等了很久還是沒人為 DS216play 編譯 tmux ，一直很搞不懂，直到我翻了這張表出來：

https://www.synology.com/en-global/knowledgebase/DSM/tutorial/General/What_kind_of_CPU_does_my_NAS_have

System Model CPU Model Cores Threads FPU Package Arch RAM
DS216play STM STiH412 Dual Core 2 Yes Monaco DDR3 1 GB

好的，看起來有點冷門的 STM STiH412/Monaco 囧，不過找一些討論串才知道，由於要讓 DS216play 可以做一些多媒體影音的事，所以，就別抱怨了 XD
