setup.py now uses CC from environment first to discover multiarch
and cross compile paths. The sysconfig variable contains the value for
the build host.

The patch also re-arranges set_compiler_executables,
configure_compiler, and init_inc_lib_dirs to make the code
easier to follow.

``setup.py`` now uses ``CC`` from environment first to discover multiarch
and cross compile paths. The sysconfig variable contains the value for
the build host.

The patch also re-arranges ``set_compiler_executables``,
``configure_compiler``, and ``init_inc_lib_dirs`` to make the code
easier to follow.

Hi! The buildbot s390x Fedora Clang Installed 3.10 has failed when building commit 545aebd.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/690/builds/488) and take a look at the build logs.
  4. Check if the failure is related to this commit (545aebd) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.
