[PATCH 1/1] tools build: Don't assume libtracefs-devel is always available

[Arnaldo Carvalho de Melo <acme@kernel.org>]

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.

Noticed after applying Ian Roger's removal unused libtracefs
configuration in tools/perf/.
