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.

66473201eb dhrystone baremetal!!! 
Factor out --optimization-level and --static to all builds

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

d1be4b2386 Allow extra make args to ./build-qemu -- arg0 arg1 
configure args are now ./build-qemu --extra-config-args '"aa a" bb'

Also factor out arg names with other builds through _add_argument.

Fix #113.

The Linux boot was still broken after the previous gem5 update. Let's try
a new one...

Add the --no-ccache option to benchmark builds.

0fdd354551 gem5: gem-regression downloads test binaries to a fixed location outside of source tree with the newly added --bin-path option 
Otherwise each --gem5-worktree would download its own copy of the test
binaries into its own source tree.

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."

daf6c890b2 Don't copy static userland builds into out_rootfs_overlay by default. 
I was doing that by mistake too often. To force it, use --copy-overlay.

This mechanism might also be useful for future userland content.

adf3ab1288 --gem5-clang takes precedence over --gem5-worktree in setting --build-id 
We are more likely to want to do a clang master test build separate from
the main master.

3808df4175 common: rename --clang to --gem5-clang 
The option was hard to understand, and this would cause ambiguity
if we ever support something else with the same option, e.g. rootfs
or userland executables.

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.
