Subject: lib, traceevent: add PRINT_HEX_STR variant
Add support for the __print_hex_str() macro that was added for
tracing, so that user space tools such as perf can understand
it as well.

Subject: 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/.
