perf doesn't use libtracefs and so it doesn't make sense to assume it is always available when building test-all.bin, defeating the feature check speedup it provides. The other tools/build/ users such as rtla, rv, etc call $(feature_check libtracefs) to check its availability instead of using the test-all.bin mechanism, stopping the build and asking for libtracefs-devel to be installed. Remove it from FEATURE_TESTS_BASIC to not have it as available, as noted by Ian Rogers during review.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
