[Bug 1635706] [NEW] gcc 6 outputs a shared object by default instead of an executable

[Hadrien]

Public bug reported:

Ubuntu 16.10 with gcc version 6.2.0 20161005 (Ubuntu 6.2.0-5ubuntu12)

* Install gcc: sudo apt install build-essential
* Build any program with gcc.
    Minimal example: printf "int main() { return 1; }" | gcc -x c -
* Read the output file header: readelf -h a.out

Expected result: the ELF header Type shows: EXEC
Actual result: the ELF header Type shows: DYN

The side effect is that we cannot run any program built with gcc 6 from
Nautilus. Nautilus opens an error message saying it does not know how to
handle a shared library.

Everything was fine with the gcc release in Ubuntu 16.04
