libtool: Fix problem with libtoolize in multilib installations

Without this patch /usr/bin/libtoolize is different for each multilib
since their host-triplets are different, despite there being no difference in
the functionality of libtoolize itself.

This change just patches out the problematic line since its just a comment for the user
in help text. Ugly but solves the problem. This fixes issues where libtool and
libXX-libtool couldn't be installed into the same system.
