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.

9076c1d9bc parsec: general cleanup, retest everything
Get rid of br2_parsec, since there are just too many possible variations on that file.

Blow up the gem5 vs qemu table to make it saner, add missing aarch64 entries.

Make sections titles describing number of cores and memory size emulator agnostic.

9fd72c786f Move all build and run output to out/$arch/
Most of it was present inside buildroot/output.* and the rest scattered
on top level.

This came about for the n-th time when we were reviewing QEMU trace file
locations.

On one hand, it would be cool to have per arch traces.

This made buildroot/output.${arch}~/ a natural choice.

But on the other, those traces have nothing to do with Buildroot,
and could potentially interfere with Buildroot build files.

It also feels nicer to have buildroot/ pristine source code only,
and keep all output under a single directory out/

f5065183a8 tracing: create trace2line
This lead to a re-factoring of count boot instructions, since trace2line
relies on the same tracing mechanism.

Also, now that we have common factored, I've decided to put the traces on
the out dir, to concentrate all outputs in a single place, and allow
easy switching between archs.

29908dffb2 Disable networking at runtime with lkmc_nonet cli instead of build
This is necessary because qemu and gem5 now use the same build folder.

Separate ./run -e and -f for kernel options before and after the ' - '.
This was already the better thing to do when -E was introduced,
but lkmc_nonet prompted me to do it nicer now.

Use the common script to find the out_dir on every toplevel script.

Include usage man pages on README.

17.10 failed with a similar message to: http://patchwork.ozlabs.org/patch/772848/
but applying that patch did not solve it, apparently there were fixes already
on later versions of the tracked package.
