Bug#606224: oggvideotools: oggJoin fails on powerpc

[Martin Steghöfer]

I compiled the package from source in the mentioned QEMU-emulated 
big-endian MIPS machine, so I could debug it properly. This way I found 
the culprit for this specific error. However, only very little of the 
other file reading code seems to be ready for a big-endian environment. 
There seems to be a whole lot of refactoring necessary to make the 
package endianness independent. If at all, this has to be done by upstream.

I think for the moment we should just stop building the package for 
big-endian architectures. What do you think?
