If I understand correctly what the problem is - that successfully
xz-uncompressing a file requires being on the same endian arch as the

platform-dependent at all.
That is not the issue. There are two issues:
- Compressing a file on different arches, while it produces output
that any arch can decompress, does produce *different* output.
- Compression of xz is not fast.

man xz
"When compressing, xz automatically adjusts the compression settings
downwards if the memory usage limit would be exceeded, so it is safe to
specify a high preset level even on systems that don’t have lots of RAM."
I hope we turned off this "feature" in rpm's use of xz as well.
