I've tried to run vtun-3.0.3 for blackfin board running Linux with uClibc-based userspace.
Because blackfin is no-MMU system, it lacks fork() system call.
The patch replaces fork() with vfork() where possible or just disables some functionality for simplicity.
I successfully managed to run vtun as a client on blackfin using vtund -f vtund.conf -n <session> <IP-address>.

Disabled functionality includes standalone server, up and down commands.

The patch should be applied after the patch from [patches:#21] or a manual update of config.h.in is required.

This is a great patch -- it even has a configure piece! I'd like to see it in 304 but I don't know a schedule for that.

I've also made small changes to man pages to document no-MMU oddities.
