The vmlinux file for s390 contains a currently unused entry point, which is specified in two different locations: the linker script and the makefile. As it happens both definitions are different and the linker file is broken (_start does not exist) and the makefile specifies an entry point which makes no sense (the SALIPL loader entry point). So lets get rid of one definition (the makefile) and use the entry point of all other ipl methods (0x10000 -> startup) to be consistent.
