From: Jiri Olsa <jo...@kernel.org>

We need a way to specify $(lib) part of the installation path for
traceevent plugin libraries. Currently we use 'lib64' for x86_64 and
'lib' otherwise.

Instead of listing all possible values, this change allows the rpm spec
code to specify the correct $(lib) part based on processed architecture,
like

  $ make ... lib=%{_lib}
