65d33ab11e run: actually rename ./run --busybox-init to --eval-after 
Had just changed the CLI parameter but nothing else!

Had half worked because Python argparse is insane and accepts substrings
like --eval-a.

Fix #43

8fb9db3931 manually encode newlines on all printed commands 
This way we group key value arguments: e.g.:

    make \
    -j 8 \
    all

instead of:

    make \
    -j \
    8 \
    all

and reach CLI nirvana, while also subtly breaking several commands due to
lack of testing.

a29b5a41fb gem5: expose syscall emulation with --user 
Then also expose QEMU user mode with --user. Docs not perfect yet,
would require a build alternative for userland/ for -static and or
passing options before the QEMU userland executable with a new CLI.

bc73cebff1 Build the Linux kernel independently from Buildroot 
This will allow for other types of root filesystems that don't rely on Buildroot
to be added and used in the future.

Propagate --verbose on all build scripts to see full GCC commands.

build-all: allow for neat subsets

also 9p share rootfs_overlay. TODO document.

74b51fc044 gem5: update to 7bfb7f3a43f382eb49853f47b140bfd6caad0fb8 
The update is required to include 3c3ca64b5f0dd9eef7b1ce1c65cc6e8e9147dd38
otherwise baremetal does not on VExpress.

baremetal: create a baremetal setup with crosstool-ng

buildroot: improve directory location: move out/dl inside
out/buildroot/download, and add a new out/buildroot/build level

tagline: generalize, deliver more value than howto, since now howtos
are starting to multiply

rename all top scripts to separate words with hyphen more consistently,
e.g. run-gdb instead of rungdb

getvar: list all variables

gem5: make m5out section to focus all releated information at

Prevent m5term Text file busy when rebuilding gem5 while it is running.

b2238daee3 Split test kernel modules to a separate script. 
Notice that Python sucks and does SIGPIPE annoyances, for now work around
by grepping the output file...

Fix the exit status read check with 'b', it broke down occasionally with:
