Bug description:
  Release of Ubuntu being used
  ============================

  Description:    Ubuntu 16.10
  Release:        16.10

  Version of the package being used
  =================================

  gcc:
    Installed: 4:6.1.1-1ubuntu2
    Candidate: 4:6.1.1-1ubuntu2
    Version table:
   *** 4:6.1.1-1ubuntu2 500
          500 http://archive.ubuntu.com/ubuntu yakkety/main amd64 Packages
          100 /var/lib/dpkg/status

  What was expected
  =================

  Programs compiled using `gcc -o program program.c` should be runnable
  by double-clicking them from a GUI file manager.

  Compiling a simple program (`void main() { }`) using Xubuntu 16.04's
  current version of `gcc` (`gcc version 5.4.0 20160609 (Ubuntu
  5.4.0-6ubuntu1~16.04.2)`) produces the following output from
  `/usr/bin/file program`:

      program: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
  dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for
  GNU/Linux 2.6.32, BuildID[sha1]=signature_here, not stripped

  This is correct behavior, allowing the executables to run from
  Nautilus and Thunar.

  What happened instead
  =====================

  Programs compiled using `gcc -o program program.c` are not runnable by
  double-clicking them from a GUI file manager, even though they are
  runnable from the terminal.

  Compiling a simple program (`void main() { }`) using the current
  version of `gcc` (`6.2.0 20161005 (Ubuntu 6.2.0-5ubuntu12)`) produces
  the following output from `/usr/bin/file program`:

      program: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
  dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for
  GNU/Linux 2.6.32, BuildID[sha1]=signature_here, not stripped

  The program is also identified as a "shared library" instead of an
  "executable" in Thunar, causing it to not be runnable from the GUI.
  Others are unable to run such programs from Nautilus.
