Since we always remove them without checking CT_HOST, we need to
create them without checking CT_HOST either.

Again, this is all wrong on multi-arch'ed systems (e.g. Fedora).

You must not symlink 32bit libraries to 64bit libraries and vice versa.

This is actually creating a place for the crosstool-NG tools to put
build libraries as they're built; it's not the system libraries
themselves.

And, once again, my build completed with this patch, and it died
without it.
Again, this doesn't mean anything.

   Note that these symlinks are deleted without any
conditional in do_finish:

     # Remove the lib* symlinks, now:
     # The symlinks are needed only during the build process.
     # The final gcc will still search those dirs, but will also search
     # the standard lib/ dirs, so we can get rid of the symlinks
     for d in                            \
         "${CT_PREFIX_DIR}"              \
         "${CT_SYSROOT_DIR}"             \
         "${CT_SYSROOT_DIR}/usr"         \
         "${CT_PREFIX_DIR}/${CT_TARGET}" \
     ; do
         CT_DoExecLog ALL rm -f "${d}/lib32"
         CT_DoExecLog ALL rm -f "${d}/lib64"
     done

When I tried to use the stock version of crosstool-NG.sh.in, the build
failed at the end because the lib64 directory was created and had
"libiberty.a" within it.
Right, crosstools doesn't handle multilibs/multiarchs correctly ... nor does your approach.
