perf tools: Allow to specify lib compile variable for spec usage
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}
