CPU Arch Detection

[Mike Barnes]

I was building up a few packages for CentOS (I wanted DVD playback, 
basically), and noticed something about building for an "alphaev6" target.

The build process works OK - I produced a xine-lib that performs a LOT 
better than the default - and things WORK when installed. The snag is 
that RPM doesn't recognise alphaev6 as a suitable architecture on my 
DS10. I have to use --ignorearch.

I remember hitting this a while back, building an EV6 optimisied glibc 
for Alpha Core, and I think we worked out this down to a bug in uname, 
not reporting the variation properly, but I can't recall the full details.

Did anyone get this sorted, or does anyone know what might need patching up?



Oh, and if anyone wants the CentOS packages for Xine, see:
http://alphacore.info/files/centos/

DVD playback is fine when using the EV6 xine-lib on a 466MHz DS10. It's 
just barely coping, though. Anything faster should be fine. There's a 
totem-xine package there too, which seems to run a little better than 
Xine itself.

SRPMs are unmodified from the DAG repository, just rebuilt for CentOS 
4.2/Alpha. I'll do some Alpha Core builds once 2.0 releases.
