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.
