I have cross-built a Linux for our embedded PowerPC boards for many years
now. I remember the early days when almost everything complained about cross
building.
Over the last year or so, I have switched to using OpenEmbedded and have seen
far fewer cross-building problems. The OpenEmbedded build system probably
contributes to the success too.
So my contention is based on many years Linux embedded work. Your milage
may vary, I guess.

I have to build boot code, linux kernel, kernel modules (drivers etc), and
all the standard Linux/GNU software (from init to shells to utilities etc).
I must admit that I have no need for things like graphics adapters, cd/dvd
drives (or any disk drives at all), keyboards/misc, etc. so I suppose you
could say that most of the stuff I deal with is "simple".
But in the end, it depends on the author of the "package" and how well they
write their autoconf scripts. You can work out most things about the target
environment in a cross-building friendly fashion.

Fair enough - so how good is the cross-building support for OpenSolaris? e.g.
Will I have much work ahead of me to build OpenSolaris for a PowerPC target
on Solaris 10/x86? Cheers!
