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

don't handle "romtype" at all, in board target.cfg files
add /dev/null as pike2008 rom on amd boards. this serves
the same purpose, adding them as empty vga roms, to add
an empty rom in cbfs. pike2008 cards cause seabios to hang,
when their oproms are executed, so we insert a fake rom
on i945 thinkpads, use the coreboot config option:
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK
when set, this enables the same bootblock copy, for use
with bucts. these two cases, namely pike2008 roms and
i945 bootblock copies, no longer need to be handled in code

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.

i previously added this just for kicks, but it's not
actually needed; gnat isn't used on fam15h boards so
lbmk doesn't even use it (it's disabled).
in fact, i tested lbmk with crossgcc_ada handling
taken out, but with said patch; i still got build
errors with gnat anyway, on that old coreboot
revision (but gnat isn't needed there anymore).
