[v3,0/2] Wrap EFL binaries into ISO images

Message

This patch set make use of tool 'grub-mkrescue' to wrap ELF binaries 
into bootable ISO images.

Cases in kvm-unit-tests can be run with QEMU. But the problem is that
some newer VMMs such as Crosvm/Cloud-hyperviosr does NOT support 
multiboot protocol with which QEMU loads and executes those testing 
binaries correctly. This patch set can wrap each kvm-unit-tests EFL 
binaries into a bootable ISO image aiming to adapt it to more usage 
scenarios. As we know, all PC BIOSes and vBIOSes know how to boot 
from a ISO from CD-ROM drive, hence it can extend the KVM-unit-tests 
a lot.

The patch set provides two approaches to create ISO. One is via 
"make iso". It wrap each ELF in foler x86 into a ISO without any 
parameters passed to the test cases.  The other is via script 
create_iso.sh. The script wraps the ELF according to the configure
file unittests.cfg which descripes various parameters for each testing.

Patch History:
V1: Initial version.
V2: Add the second parament to the script create_iso.sh, that could 
pass environment variables into test cases via the file.
V3: Add some failure handle.

Thanks for doing that. I find your work very useful (at least for me).

For what it worth in kvm-unit-tests, I should have gave before:
