Running make check-tcg-x86_64 on a big-endian host (e.g., s390x) fails due

qemu-system-x86_64: Error loading uncompressed kernel without PVH ELF Note
There already exists logic in include/hw/elf_ops.h.inc to handle byte-swaps
where necessary, but it does not perform this logic for ELF notes itself.
Fixing that improves matters, but yields other errors: most of the tests
timeout while some generate confusing assertions. Both appear to be related
to the data addresses in those notes, which are incorrect when running on a
big-endian host.
Adding tswap wrappers, which will conditionally swap if the host and target
endianness don't match, fixes that such that check-tcg-x86_64 runs cleanly
on an s390 host.

Hi!
This looks like a good addition for the stable series, if it actually
fixed the issue mentioned.
I'm queuing this change for the stable series, but not picking for any
release just yet, - if a follow-up fix will come, I'll include both.
And please let me know if I shouldn't :)
Thanks,
/mjt
