I use a variation on my own LFS system (Basically 64bit goes into
/usr/lib, and 32bit to /usr/lib/32.  If there are binaries I want, I
install them to /usr/lib/32/bin).

I also have a couple cross compilers, which are currently at
/usr/x86_64-pc-mingw32 and /usr/x86_64-pc-apple-darwin10 (Which would
probably be better in a multiarch setup).  Also have a lfs to ubuntu
(/usr/x86_64-ubuntu1204-pc-linux-gnu) cross compiler, but I couldn't
get the multiarch patches to work for me (autotools failed to
regenerate the build system).  I cheated and moved all the libraries
to standard locations instead


I was tossing the multiarch idea around,  but there would be a lot of
modifications to my buildscripts to use /usr/lib/x86_64-pc-linux-gnu
instead of /usr/lib.  (I don't mind doing that for the i686 arch, as I
rarely use 32bit software [I think just wine right now], but otherwise
I do try to keep close to LFS/BLFS upstream).  I think using
/usr/lib/i686-pc-linux-gnu instead of /usr/lib/32 would be great
though.

I'll update my notes at http://www.nathancoulson.com/proj_lfs.php (I
think when I put up that page, I couldn't adapt the existing gcc
instructions (We were using -B) for a multilib setup).  Not really a
multiarch system, but it does modify some of the paths.
