The linker cannot find some libraries

[Joelcgx]

i have ffmpeg 2.8.12
I'm trying to cross-compile for Android from Ubuntu x86_64, when linking the libraries it fails (sorry for my bad English), I've been trying for over a week and I can't, I would appreciate it if you could help me, maybe I'm doing something wrong.
