c1f060ca65 test-gdb: find source path correctly 
Previously was relying on glob order, and which could pick up the .py
instead of the .c / .S.

72167f9f68 bring a minimal buildroot kernel modules example to life 
More importantly, to make modules_install on the Linux kernel build.

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.

ca231b82f6 get rid of lkmc package, move userland and kernel-modules to top 
Rationale: we already had a non buildroot build system,
maintaining both will be hard, and having short paths is more awesome.

dae60aa248 modules: rename packages/kernel_modules to packages/lkmc 
Then inside, split packages/lkmc into kernel_modules and userland,
to keep userland out of the kernel_modules parent path, which makes no
sense.

Copy built modules and userland to the output rootfs overlay.

Document Linux distro tradeoffs.

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:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 1832: invalid start byte
