Some versions of GCC don't accept `-no-pie`. For instance, on a GCC 5 build I
have here:

```
$ gcc -no-pie
gcc: error: unrecognized command line option ‘-no-pie’
gcc: fatal error: no input files
```

5.4 from Xenial will take `-no-pie`, as will versions of 4, 6 and 7 that I
tried. The issue may be related to
https://www.mail-archive.com/gcc-patches@gcc.gnu.org/msg170818.html but I'm not
certain.

A workaround for this is to use `--no-pie`, which is accepted by all versions
of GCC 4, 5, 6 and 7 that I tried.
