JIT compiler causes crashes on FreeBSD 11.1 11.2 RELEASE

[openssservices]

When running dynamips it crashes every time with the following error:

FreeBSD 11.1 and 11.2 RELEASE are effected.

On a personal note I would love to get this running so I can run VMs in GNS3 2.0.3!

Bug also posted to FreeBSD bugzilla: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222047

Possible solution is to compile the 32-bit version of Dynamips: https://github.com/GNS3/dynamips/issues/83#issuecomment-363770174

The backtrace points to strftime, so this is probably fixed by #229
