Not too long ago (QEMU 5.0) it was possible to configure with --disable-tools
and still have virtiofsd built. With the recent port of the build system to
Meson, it is now built together with the tools though.
The Kata Containers [1] project build QEMU with --disable-tools to decrease the
attack surface
---enable-tools only adds separate executables, therefore it can't add to the attack surface of the emulators. So this is misleading.
That said, it does make sense to let --enable-virtiofsd override --disable-tools, and the same in the other direction too.

Side note: in a private chat with Stefan Hajnoczi he come up with the idea
that perhaps --disable-tools could be like --without-default-features where
one can add back on feature-by-feature basis. This is outside the scope of this
series but I thought in sharing because IMHO it is deserves a discussion.
