It's a pretty rare issue these days.  You have to provide an absolute 
pathname, which is always frowned upon.  Further, if you cross-build in 
a chroot, it's a non-issue.

Yep- but only relevant for a small set of packages.

Gcj?!  Er, no problem there...

I'm sure there could be some Python issues (We have not had to tackle 
that one).  When we start implementing a cross compile feature, we would 
naturally would take on the easy and critical packages first.  Python 
could come later.

Great!
