I'm just going to shamelessly quote the FreeBSD Quarterly Status Report, Q4/2016 that came out a few days ago.

   LLD developers made significant progress over the last quarter. With
   changes committed to both LLD and FreeBSD we reached a major milestone:
   it is now possible to link the entire FreeBSD/amd64 base system (kernel
   and userland) with LLD.

   Now that the base system links with LLD, we have started investigating
   linking applications in the ports tree with LLD. Through this process
   we are identifying limitations or bugs in both LLD and a number of
   FreeBSD ports. With a few work-in-progress patches we can link
   approximately 95% of the ports collection with LLD on amd64.

That is 95% of ~27000 ports. Which means for very many things, lld as linker will just work once those patches have been applied at the appropriate places.
