Bumping lttng-libust to 2.1.2, or 2.2.0-rc1, does not fix the problem.
However, adding this patch (from Yocto) to crosstool-NG does fix this
lttng-libust build issue:
So, I think now it's Yann's call to integrate this patch in crosstool-NG.
Note that this patch does not seem applied upstream since it can be
applied on all the following branches of gcc:
gcc-4_6-branch, gcc-4_7-branch gcc-4_8-branch, master.
