That is where I would expect sse2 information; either inline or a pointer
to something more comprehensive.

Not much is using sse2 right now. I would expect that the main ogre package
could make use of this, but currently doesn't.

I am having trouble finding good documentation on what the runtime linker
does. The link below is the best description I have found so far, and answers
a question I had about whether stuff needs to be in /usr/lib/sse2/OGRE or
/usr/lib/OGRE/sse2 (the former).

I think I know enough to attempt a -sse2 subpackage for x86 arch.
The path to proven packager is paved with much learning.
