Create full static binary need option

[centosup]

Please add option for create full static binary without system libraries dependencies.

I want to compile code on Debian and run on CentOS, but this is impossible because LibC, Libptheads and some other libs are dynamic

Look at projects https://github.com/zimbatm/ffmpeg-static - this is full static buld and I can comple this in Ubuntu and run on the CentOS.

Thank you 😊
