Well, obviously you HAVE to cross-compile to port to a platform Solaris doesn't
yet work on. :-)
Yes, the amd64 port was aided by the fact that the same hardware could be
booted
back into 32-bit mode, but at the same time ld for amd64 had to deal with a
whole new link strategy anyway.
So while cross-building isn't "supported" at the same time it's the only way
you
can do a port. What remains as an exercise for the user is whether it's easier
to make Sun's ld generate a PPC binary on SPARC or x86 Solaris or on PPC Linux.
