This puts us in a weird situation where ~/git/qemu is default for CXL, but there's no default outside of CXL.
Also with CXL support soon to start appearing in upstream releases, and distros thereafter, I wonder if it is time to drop the CXL special case requirement of git-qemu altogether.

So this essentially duplicates the env way of setting qemu's location -
qemu=/path/to/qemu/binary run_qemu.sh ...
--git-qemu was supposed to be a shortcut to make that default to ~/git/qemu which happened to be the path in my case :)
Now that the user base is slightly bigger, I think it makes sense to clean it all up a bit:
- We can convert to --git=qemu= going forward, and make ~git/qemu the default in parser_generator.m4
- make
qemu=<path> run_qemu.sh ...behave the same way (probably already the case) - Remove the special case behavior for --cxl
Thoughts on this?

Can we get rid of all of these special cases and just use the env way of setting qemu? Let's assume cxl support moving forward, and figure out a way to add a check for cxl support if --cxl is set, maybe check qemu version?

I would rather drop the environment way because environments variables are sneaky and evil :-)
While CXL support in QEMU is mainstream now, I think it would be good to keep just ONE way to override it, at the very least for testing purposes.

There are conflicts now, this needs a rebase.

Or, even better: Can "argbash" do that? For sure the shell can tell the difference between unset versus set empty when you ask nicely https://pubs.opengroup.org/onlinepubs/7990989775/xcu/chap2.html#tag_001_006_002 |
