[PATCH v2 1/4] feature: realize libzstd check, LIBZSTD_DIR and NO_LIBZSTD defines
Implement libzstd feature check, NO_LIBZSTD and LIBZSTD_DIR defines
to override Zstd library sources or disable the feature from the
command line:
$ make -C tools/perf LIBZSTD_DIR=/root/abudanko/zstd-1.3.7 clean all
$ make -C tools/perf NO_LIBZSTD=1 clean all
