s390: fix strrchr() implementation
Fix two problems found in the strrchr() implementation for s390
architectures: evaluate empty strings (return the string address instead of
NULL, if '\0' is passed as second argument); evaluate the first character
of non-empty strings (the current implementation stops at the second).
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
