[PATCH 0/2] build: fix "make check" without earlier "make"

[Paolo Bonzini]

"make check" without a previous "make" will not build the tools
needed by qemu-iotests.  This happens because "make check-block"
does not do the Makefile magic that causes ninja to build the
test dependencies.

This could be fixed by making qemu-iotests a Meson test, which is
coming indeed; but in the meanwhile copy the mechanism used by
Makefile.mtest, just adapted to check-block's dependencies.

qemu-iotests run qemu-storage-daemon, make sure it is up to date.

Subject: [PATCH 2/2] build: fix "make check" without earlier "make"

"make check", if not preceded by "make", will not build the tools
needed by qemu-iotests.  This happens because qemu-iotests, aka
"make check-block", is not yet part of meson.build.
