working s3 means i'm happy to mark it as being stable.

it should be marked unstable, though these machines
are basically reliable; they have certain missing features
and quirky behaviour so it's important not to over-sell it

mark it as unstable, on all of the dell latitudes

some latitudes still used the old style for variables
in target.cfg, specifically arch="x86_64" - lbmk used to
then check that on a big if/else and translate it to the
correct target name for crossgcc, e.g. i386-elf, arm-eabi

now it just puts the arch directly, in a new variable:
xarch

change arch="x86_64" to xarch="i386-elf" in these files.
also remove a few obsolete variables. should build now.

also warn about issues, in a warn.txt file for each.

export LBMK_VERSION_TYPE=x
x can be: stable, unstable

in target.cfg files, specify:
status=x
x can be: stable, unstable, broken, untested
if unset, lbmk defaults to "unknown"

if LBMK_VERSION_TYPE is set, no confirmation is asked
if the given target matches what's set (but what's set
in that environmental variable can only be stable or
unstable)

if LBMK_RELEASE="y", no confirmation is asked, unless
the target is something other than stable/unstable

"unstable" means it works, but has a few non-breaking
bugs, e.g. broken s3 on dell e6400

whereas, if raminit regularly fails or it is so absolutely
unreliable as to be unusable, then the board should be
declared "broken"

untested means: it has not been tested

With this change, it should now be easier to track whether
a given board is tested, in preparation for releases. When
working on trees/boards, status can be set for targets.

Also: in the board directory, you can add a "warn.txt" file
which will display a message. For example, if a board has a
particular quirk to watch out for, write that there. The message
will be printed during the build process, to stdout.

If status is anything *other* than stable, or it is unstable
but LBMK_VERSION_TYPE is not set to "unstable", and not building
a release, a confirmation is passed.

If the board is not specified as stable or unstable, during
a release build, the build is skipped and the ROM is not
provided in that release; this is in *addition* to
release="n" or release="y" that can be set in target.cfg,
which will skip the release build for that target if "n"
