The zx1_defconfig in ia64 tree has CONFIG_CRYPTO_BLK_CONFIG=y ... making
these symbols not only causes build warnings:
chainiv_module_exit' referenced in section `.init.text' of
crypto/built-in.o: defined in discarded section `.exit.text'
eseqiv_module_exit' referenced in section `__ksymtab_gpl' of
crypto/built-in.o: defined in discarded section `.exit.text'

it also manages to make my "ld" dump core!
