Ah, I see now. The XZ package provides liblzma and it should be picked
up by configure. The other libs (zlib and bz2) only accidentally work
- configure tests the native versions and it just so happens that the
cross-gcc can find the right ones at build time. I imagine if I had xz
installed it would work the same.

This is a small enough configure.ac so I might see if I can make it
more cross-compile friendly.
