[opus] Linux opus-tools static builds.

[bat guano]

Hi
Some Linux programs are 'static'.
For example, these FFmpegs here ---> http://ffmpeg.gusari.org/static/

If we compile with Linux
opusdec & opusenc & opusinfo & opusrtp
using only static libraries
libogg.a & libflac.a & libopus.a

Are the four opus-tools programs then genuinely 'static', so that they will work on *any* Linux OS?

$ ./opusenc -V
opusenc opus-tools 0.1.7-10-g7c3f522 (using libopus 1.1-beta-51-gaee4d80)

$ ldd ./opusenc
