This commit introduces a new vhost-user device for block, it uses a
chardev to connect with the backend, same with Qemu virito-blk device,
Guest OS still uses the virtio-blk frontend driver.
To use it, start QEMU with command line like this:

Add a function to return ELF e_flags and use it
to select the CPU model.
[lv: split the patch and some cleanup in get_elf_eflags()]

Notes:
YunQiang Su, please add your Signed-off-by that was
missing in
Instead of a sequence of "#if ... #endif" move the
selection to a function in linux-user/*/target_elf.h
We can't add them in linux-user/*/target_cpu.h
because we will need to include "elf.h" to
use ELF flags with eflags, and including
"elf.h" in "target_cpu.h" introduces some
conflicts in elfload.
