Comment (by heleppkes):

 The presence of the instructions in the avcodec library should not prevent
 it from running on any system, as its designed to detect the CPU features
 and only execute the code if supported.

 So does it actually fail to run? That seems rather weird. None of the libs
 should ever execute it if your CPU doesn't support it.

 Maybe your C++ compiler/linker somehow scans the static library for all
 instructions it uses and then somehow flags the resulting library to
 require these? That seems like a rather crazy thing to do, but what do I
 know about the oracle tools on Solaris.
