Does GNU/kFreeBSD has a Sid distribution?

Hi mentors,

I am currently doing my packaging work on Debian Sid (amd64). It
builds fine on it. Now I am trying to port the package to other
architectures. It seems that GNU/kFreeBSD does not have a Sid
distritution, is it true? I want to use Sid to do my packaging work
because the software I package is computational-intensive, it is worth
using the latest GCC version to get best optimizations. Should I make
a sperate package for GNU/kFreeBSD? Any advice will be helpful!

Thanks,
Alex
