Heh, this "just have to export" turned into a series of
patches. The library was only included into the build
when configured to use it for actual gfxinit. But I got
something to compile, untested though: CB:31458. It
includes an update to the submodule pointer with wip
changes to libgfxinit, so that requires a manual fetch
there:
    cd 3rdparty/libgfxinit
    git fetch https://review.coreboot.org/libgfxinit refs/changes/54/31454/3

Oh, and I realize now, it's not hooked up for all sup-
ported platforms yet.
