[PATCH] Fix build with CONFIG_KCORE_AOUT

We get a linkage error with CONFIG_KCORE_AOUT because there is no
implementation of kclist_add() and kclist_del().

Also fix a warning in the a.out version of read_kcore().

Maybe we should just remove kcore a.out support.  m68knommu and h8300 are
setting CONFIG_KCORE_AOUT in their defconfigs though.
