- This unbreaks lttng linux kernel modules[1]
- lttng-tools has grown a dependency on libxml2
[1]: Build tested (for default NixOS Linux kernel) and run tested with
lttng-sessiond (it successfully loads kernel modules).
(And update liburcu to 0.8.4 according to release notes for lttng 2.4.x.)
In addition to new features and bug fixes, version 2.4.x is needed to build
against Linux 3.12 (our new stable kernel).
