it doesn't build, at present, but isn't used by any
coreboot targets, so the build issue does not come up
during release builds, but i did find it laying around
during my audits.

x86 qemu is on todo for libreboot, on all x86 boards,
but the current config is broken, so: remove it.

it's very much a requirement that anything in lbmk should
work.

let them specific it, rather than falling back
to coreboot/default (can also be used for coreboot boards)

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch

the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets

crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.

without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.

the new logic, as per this patch, is simpler and more robust.

Add a U-Boot build for the qemu_x86_12mb board. The config is a copy of
the upstream "coreboot" defconfig, but with OF_EMBED=y.
