The lttng-ust README file states to run ./bootstrap before configure.

git clone git://git.lttng.org/lttng-ust.git
cd lttng-ust
#then either:
git checkout master (for master branch)

# or
git checkout stable-2.0

Side-note: the linking problem you are seeing might be caused by an
issue in lttng-ust Makefile.am regarding support for cross-compiling.
Unfortunately, I don't have a setup readily available, but if other
people could test cross-build and report issues, it might help us.

Thanks!

Mathieu
