From: Kai Kang <kai.kang@windriver.com>

As in the lttng manual [1]:

Most distributions mark the LTTng-modules and LTTng-UST packages as
optional when installing LTTng-tools (which is always required). In
the following sections, we always provide the steps to install all
three, but note that:

* You only need to install LTTng-modules if you intend to use the
Linux kernel LTTng tracer.
* You only need to install LTTng-UST if you intend to use the user
space LTTng tracer.

there should be no force dependency between lttng-tools and
lttng-modules. When set lttng-modules in RRECOMMENDS, it always forces
to build lttng-modules whether it is required or not.

Compare to rpm spec [2] and debian conf [3], there are no any dependency
between them too.

So remove the RRECOMMENDS setting.
