There's no use for these utilities in FreeBSD base system.

llvm-{as,ld,ar} are not replacements for those from binutils. llvm-*
work on the llvm bitcode only and are of no use for normal object
files.

dim@ made a patch that adds those utilities if you really need them

http://lists.freebsd.org/pipermail/freebsd-toolchain/2011-June/000216.html

By default when you compile things with clang it uses its own assembler
(ie. it goes directly from C -> .o) so typically only gnu ld is used
in the compilation chain.
