With the conversion to meson and removing the old QEMU Makefile
baggage we became very silent when building the plugins. Bring in a
copy of the quiet-command logic (and some magic COMMAs) so we can at
least assure developers we are building them.

Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2457

Maybe we should just move to a meson build as proposed here:
