i overlooked these in the previous revision

do this with board.cfg option:

crossgcc_ada="n"

add this environmental variable when building
crossgcc, if crossgcc_ada="n":

BUILD_LANGUAGES=c

This avoids building the GNAT/Ada compiler in GCC.
Coreboot 4.11 is only used for some AGESA boards
that don't need Ada (their video init is the old
style, written in C, it's not libgfxinit)

also kfsn4-dre

this is still based on the old coreboot 4.11 version.

i have on todo to adapt dasharo coreboot for use in the master
branch of lbmk, for mainline libreboot releases.

since i'm doing c-libreboot for the GNU project, namely GNU Boot,
and since GNU Boot has dre/d8/d16 in their tree, re-add it here
for them.

i literally just copied this from them, who in turn copied it from
libreboot in an older revision anyway.

but there is one fix:

src/vendorcode/cavium/bdk/libbdk-hal/if/bdk-if-phy-vetesse.c

^ this blob wasn't being deleted by gnuboot, nor by libreboot
in the older revision that it forked from. an oversight. i decided
to audit the deblobbing and found this one was overlooked, out of
about 900 files picked up by deblob-check.

so this re-addition of dre/d8/d16 support is actually even better
deblobbed than gnuboot, or old-libreboot.

buggy, buggy, buggy, buggy, buggy, buggy, buggy

full of bugs, these boards never worked properly. i got ripped
off with these.

now i'm ripping off the band aid

use dasharo if you want d16 stuff. i'm done with it.

osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.

tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.

i don't trust tianocore, so i'm removing it.

libgfxinit_txtmode with seabios only
