f738f296ea s390x/arch_dump: pass cpuid into notes sections
we need to pass the cpuid into the pid field of the notes
section, otherwise the notes for different CPUs all have 0:

e.g. objdump -h shows:

5f706fdc16 s390x/arch_dump: use proper note name and note size
In binutils/libbfd (bfd/elf.c) it is enforced that all s390
specific ELF notes like e.g. NT_S390_PREFIX or NT_S390_CTRS
have "LINUX" specified as note name and that the namesz is
6. Otherwise the notes are ignored.

QEMU currently uses "CORE" for these notes. Up to now this has
not been a real problem because the dump analysis tool "crash"
does handle that. But it will break all programs that use libbfd
for processing ELF notes.

So fix this and use "LINUX" for all s390 specific notes to comply
with libbfd. Also set the correct namesz.

fcf5ef2ab5 Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
