I'm aware. I can read, really ;-)
But automated build tools won't know.

And this causes, that the build order matters.

We're no longer able to build qemu without usbredir when usbredir
is somehow already present, because there's no way to pass
--disable-usbredir to the qemu.Slackbuild.

And what I'm really trying to say here is, that qemu without
usbredir is missing an important feature and qemu without
usbredir will make the virt-manager viewer unusable.

So maybe usbredir should be considered as REQUIRED
or at least there should be a switch for qemu.Slackbuild
available, which would stop the build if usbredir is missing,
so we have more control, or a switch allowing us to pass
--disable-usbredir if we're building on a system, where
usbredir is already installed.

Before 14.1 usbredir was optional, because the official libusb
was too old, that's not the case anymore.
