[2/4] mesos git commit: Removed the use of `FORTIFY_SOURCE` from stout.

[mp...@apache.org]

Removed the use of `FORTIFY_SOURCE` from stout.

`FORTIFY_SOURCE` is no longer used when hardening. This is to prevent
the warning that some versions of gcc/libc throw when `FORTIFY_SOURCE`
is used without optimizations. The warning turns into an error via
`-Werror` and fails the whole build.
