projects/clang600-import and ld.lld

[Shawn Webb]

Hey All,

I know it's early in the game, but I thought I'd report this anyways.
I have lld as the default linker (MK_LLD_IS_LD=yes). When lld tries to
link usr.bin/clang/llvm-extract/llvm-extract, lld errors out with some
unresolved symbols. The log is below.

Has anyone else run into this?
