c0bc5cffed pass disk image to baremetal if present 
Why not? But this is mostly a cheap workaround for gem5 baremetal not
handling no disk images.

Factor out --optimization-level and --static to all builds

More conventionally set argv[0] to be the basename of the image.

f2713e69f6 Don't pass dummy disk images to gem5 
After https://gem5.atlassian.net/browse/GEM5-337:

- gem5 baremetal can run without any disk images, just like QEMU
- gem5 X86 can run with a single disk image and no horrendous dummy vmlinux
  and second disk image

This notably allow dynamic linking to work! Move entire README to it.

Also:

- explain what Dhrystone does and run it on gem5 to get DMIPS
- create getprops
- ./test-executables don't test files that start with "tmp."

d334a0db53 gem5: fix --gem5-readfile 
Was completely broken due to confusion between --gem5-readfile and a common
variable with the same name which referred to the file path... OMG.

Conclusion: no one has ever used this tutorial!

Improve ./gem5.sh documentation.

Also fix ./gem5-bench-dhrystone.

2438410c25 gem5: put m5 back in path, was in lkmc/bin/m5 
It is a dilemma to do this or not, since all other test execs are
not in /bin, but I'll go with "this is not just a random test program" for
now. Let's see.

Checkpointing: correctly sort fs.py checkpoints numerically, was only
working previously due to coincidence.

01984c2201 test-boot: run in parallel 
--quit-after-boot: fix for gem5, update path to gem5.sh

Improve the printing of results and errors:

- remove newlines from IDs at the end for ./test-boot
- remove newlines from progress for __call__ commands and don't print executed commands at all,
  otherwise there are too many lines per test and it is hard to tell what is going on
- print backtraces for any exception in the threads (bugs while developing this code)

Tests across different archs and emulators are still not running in parallel,
which is a huge loss. TODO.

thread_pool: introduce with API. This was motivate by test-boot, I've had enough
of doing separate error handling for each loop type! Greatly dries up the code, awesome.

common: make --all-emulators work properly with native hopefully for the last time,
./test-baremetal was still failing.

gem5: don't pass --command-line for baremetal. Maybe later we can use it to actually
pass command line arguments to main()? To be seen.
