Introduce the new logical option CONFIG_HAS_POST which is set when the platform has CONFIG_POST set. Use CONFIG_HAS_POST in the post/ Makefiles to determine should the POST libs be compiled for the selected target platform, or not. To avoid breaking u-boot linking process, the empty post/libpost.a file is created for platforms which do not have POSTs.
