8b77fe703b readme: kgdb only working in x86 graphic mode 
Not sure if it ever worked outside, but I guess it didn't.

Fix should be simple, but not important enough.

9e79b9b06f Save .log output files to out/arch/ 
This is cleaner as it removes yet another .gitignore rule and allows
for one command per arch.

This was prompted by the recent Docker patch creating files as root,
which then breaks future host runs.

Also separate all arguments by newlines. This:

- makes it much easier to minimize when reporting QEMU bugs
- shows the full command on the screen despite line wrapping being turned off
  by one of the annoying emulators, to be investigated.

The commands are not yet pristine, because:

- there are some leading spaces
- options not sorted

but it is already a huge improvement, and those operations are now be easy from Vim.

The general strategy is:

- end every variable containing a command with a newline
- when expanding such variables, don't add an extra newline

ecf2f3b29e build: use nproc instead of nproc - 2 
Someone was trying to build on a 1 core machine and it broke the build.

The rationale for the -2 was to leave 2 cores for your to use your computer still,
but let us trust the OS scheduler a bit more.
