It doesn't behave that way by default:

z3.local(1)$ ./sh --version
GNU bash, version 3.1.5(2)-release (powerpc-apple-darwin8.3.0)
Copyright (C) 2005 Free Software Foundation, Inc.
z3.local(1)$ ./sh -c 'echo -n ok'
okz3.local(1)$

Somehow you've enabled the xpg_echo option, either by configuring
with --enable-xpg-echo-default or running `shopt -s xpg_echo'
somewhere.  I suspect the former.
