Comment (by ryandesign):

 Looks like qemu has a bunch of features it will enable if the appropriate
 libraries are found. I didn't look at how many of them we are expecting to
 use in the portfile (based on what dependencies we set) and how many we
 aren't expecting. There is an option `--without-default-features` we could
 use to tell the build system only to enable things we explicitly tell it
 to. That might be wiser so that new features that are introduced in the
 future aren't unexpectedly enabled without the dependency having been
 added (which is what happened when jack support was added to qemu in 5.1.)
