Darwin's as is special, in that it is the one from LLVM. 
Darwin's ld (and dsymutl, lipo, and otool) is from cctools but you don't have
that installed either.

I just manually set symlink to llvm in the sysroot/bin. Would that work?

You don't have the sysroot setup or anything.
Cross compiling to darwin is not for the faint of heart and really this is not
the place to get help doing it.
