I found out that completely removing the object directory and
recreating it from scratch helps. This sucks bisectability-wise, is
there any way to avoid it?

There is still one problem, tools need config-host.h but the
dependencies are not correct:
  CC    qemu-nbd.o
In file included from /src/qemu/qemu-nbd.c:19:
/src/qemu/qemu-common.h:32:25: error: config-host.h: No such file or directory
