[lttng-dev] [PATCH lttng-tools] Fix: Missing librt dependency in configure check for lttng-ust-ctl

[Christian Babeux]

The lttng-ust-ctl library depends on librt. The AC_CHECK_LIBRARY macro
can't automatically resolve dependents libraries (ala libtool),
so any additionnals dependencies must be manually specified.
