--- Comment #1 from Dimitry Andric <dim at FreeBSD.org> ---
It looks like you are attempting to defeat the linker detection mechanism in
/usr/share/mk/bsd.linker.mk, and succeeding. :)

If you say "building a kernel using llvm70 and llvm80", can you describe
exactly how you are doing this?  As far as I know, it is not possible to build
anything with two different compilers at the same time.

Note that symlinking /usr/bin/ld to something random might or might not work,
your mileage may vary (a lot).

I think that in your case, overriding LINKER_TYPE might be the best approach. 
E.g. if you symlink /usr/bin/ld to a ports version of lld, it is safest to put
LINKER_TYPE=lld in your environment or make.conf.

All that said, it would be much easier if you just used any of the
devel/xtoolchain-llvm[6-9]0 ports.
