This has broken the Rawhide buildroot:

DEBUG backend.py:656:  /usr/bin/yum --installroot /var/lib/mock/dist-f15-build-911517-134161/root/  groupinstall build

Given that the ABI hasn't actually changed since the previous build, a
short term fix could be to build a mini liblzma.so.0 that just links to
liblzma.so.5, along the same lines as the mini libcurl built for the
last soname bump of that library (Mon Aug 11 2008, curl 7.18.2-4).

The current build needs untagging anyway.
