Turns out that the fix for this is to make sure that devel/kBuild
is compiled with GCC, not clang; thus, that module of VBox that
has global register variable (and fails to build with clang) is
automagically built with gcc. So some parts of VBox are built
with base clang, some with gcc from ports; it is awkward, but
it all works somehow.
