You forget that a "distro" is pretty much a Linux concept. There is no
such thing on W32 (openSUSE doesn't package it for MinGW either), and on
Darwin the various competing ports systems suck IMO.

On OpenBSD there's a "dtc" port but we'd need to assure it's installed
on the build bots before we mandate it, same for the Linux build bots.

I'm not objecting to mandating it but would like to propose to only
mandate it for the targets that need it. I.e., if no libfdt available,
don't install microblaze and ppc softmmu targets. That would still allow
the average user to emulate x86 or arm without hassles, and it should
not be needed for linux-user.

The pixman submodule has not been working well for me, it's not a
universally working solution to be copied either.
