The 'i686-lfs-linux-gnu' came in through the move across to DIY's build
method [0].  This is described at [1]:

"It is vitally important to ensure that the vendor field of the target
triplet is something other than "pc" or "unknown". This is because we
want to force the pass 1 toolchain into cross compilation mode. For 
example, if your real target is i686-pc-linux-gnu, set [$LFS_TGT] to
i686-[lfs]-linux-gnu or even i686-FAKE-linux-gnu."

In our chapter 5 toolchain notes this is summarised in:

"Slightly adjusting the name of the working platform ensures that the
first build of Binutils and GCC produces a compatible cross-linker and
cross-compiler. Instead of producing binaries for another architecture,
the cross-linker and cross-compiler will produce binaries compatible with
the current hardware."

A reference to LFS_TGT in the above paragraph would certainly clarify
what's going on for me and help in understanding how this all hangs
together.
