Hi Peter,
It looks like this is the culprit, from that commit:
-common-obj-y = $(block-obj-y) blockdev.o blockdev-nbd.o block/
+common-obj-y = blockdev.o blockdev-nbd.o block/
You are running into this bug since you configured with
--disable-tools.
As a temp workaround, if you build qemu-nbd (or qemu-img) first, that
should build the required block-obj-y objects, which should then allow
everything to build. E.g.:
make -j5 qemu-nbd all
