[Qemu-devel] [PULL 1/1] configure: fix LTTng UST tracing backend detection

[Stefan Hajnoczi]

From: Francis Deslauriers <francis.deslauriers@efficios.com>

The detection program needs to be linked with -ldl to build succesfully
with recent versions of LTTng-UST.

We also need to add -ldl to the libs required to build the LTTng-UST
backend (lttng_ust_libs).
