Alien OS (Linux) cross build support

[Eddy Petrișor]

Hi all,

I looked at the current code, the handbook and whatever documentation I
could find on the topic, and my conclusion was that alien OS cross building
of FreeBSD is NOT supported. Is this correct? Do I need to have a FreeBSD
host to cross build for ARM or ARM64? Can I at least build part of the
system on a non-FreeBSD host?

Was/Is there any effort going on to add this to FreeBSD, NetBSD style?
Would it be easier to support first other *BSD hosts, then maybe add Linux?
