Subject: [PATCH] module: use MODULE_SYMBOL_PREFIX with module_layout

The check_modstruct_version() needs to look up the symbol "module_layout"
in the kernel, but it does so literally and not by a C identifier.  The
trouble is that it does not include a symbol prefix for those ports that
need it (like the Blackfin and H8300 port).  So make sure we tack on the
MODULE_SYMBOL_PREFIX define to the front of it.
