The set of C compiler options used by distros to build python bindings
may include options that are unknown to clang, we check for a variety of
such options, add -fno-semantic-interposition to that mix:

This fixes the build on, among others, Manjaro Linux:

    GEN      /tmp/build/perf/python/perf.so
  clang-9: error: unknown argument: '-fno-semantic-interposition'
  error: command 'clang' failed with exit status 1
  make: Leaving directory '/git/perf/tools/perf'

  [perfbuilder@602aed1c266d ~]$ gcc -v
  Using built-in specs.
