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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
