[S390] s390: beautify vmlinux.lds
Introduce a consistent style in vmlinux.lds. This style is gradually being introduced for all archs. A few lables were moved inside the section definition so they are assigned the correct value of gcc decide to align the content to another address than the one . has. In the past this has fixed several bugs but for s390 it will not impact due to all the alignmnet already introduced. Stabs definitions are consolidated in asm-generic/vmlinux.lds.h This patch also introduce support for DWARF - without knowing if this makes sense for s390.
