release.  GDB support in UST was temporarily removed from UST by the
commit you pointed out.  GDB CVS trunk is still able to build with UST
0.11 and URCU 0.5.3.

If UST 0.11 is installed, everything still works well, otherwise, UST
stuff will not be compiled.  So I disagree to disable it temporarily.

There has been a PR for this issue,

  gdb 7.2 can't build with lttng-ust 0.12
