Some symbols are not implemented in C, or not in "arch/score", but score need export them, so add 'score_ksyms.c' to export them, just like other architectures have done.
The related error (with allmodconfig under score): MODPOST 1365 modules ERROR: "__clear_user" [drivers/md/dm-mod.ko] undefined! ERROR: "__copy_tofrom_user" [net/x25/x25.ko] undefined!
