    perf python: Filter out -specs=/a/b/c from the python binding cc options · 4be92cf0
    Arnaldo Carvalho de Melo authored
    The -spec=/path/to/file can be used to change what gcc puts in the cc,
    ld, etc command lines, but this is not present in clang, filter it out
    at the setup.py file by changing python2's internal variable where it
    keeps its initial CFLAGS value.
    
    With this all of perf can be built in at least Fedora 25, fixing this
    problem:
    
        GEN      /tmp/build/perf/python/perf.so
        CC       /tmp/build/perf/builtin-buildid-list.o
      clang-4.0: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument]
      clang-4.0: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument]
      error: command 'clang' failed with exit status 1
    
    Now I need to change all the containers where I have clang to build
    perf with it, so that we can check that in other distros (opensuse, debian,
    ubuntu, etc) this also works.
