tools perf scripting python: clang doesn't have -spec, remove it
Gcc has a -spec option to override what options to pass to cc, etc, and in some distros this is used, like in fedora, where we end up getting this passed to gcc that makes clang, that doesn't have this option to stop the build: CC /tmp/build/perf/util/scripting-engines/trace-event-python.o clang-4.0: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument] So filter this out when the compiler used is clang, this way we can build the python scripting support in tools/perf/.
