I've cross-built NetBSD releng-5, -6 and -HEAD from FreeBSD: succeeded perhaps 
a bit better than half the time for i386 but only infrequently for amd64.

FreeBSD base gcc version is 4.2.1 because that is the last version that doesn't 
use GPL 3 license.  I think that might have been less capable than a more 
up-to-date version.

There are newer versions of gcc in FreeBSD ports.

I had much better success rate building from the resulting NetBSD builds which 
were successful.

I am also thinking of cross-building Linux, at least a starter set, from 
FreeBSD or NetBSD; would surely use something newer than gcc 4.2.1.

NetBSD is a dubious proposition on my system; FreeBSD is much sturdier.
