My scconfig handles cross-compilation well. The trick is to separate the 
host env from the target env and make it just one of the cases when they 
happen to be the same.

If you need "date -d" during compilation to include the build date in the 
"about" dialog, or something similar, it's just a host thing. The strftime 
suggestion works as long as you use the host C compiler (and not the 
target C compiler which would be a cross-compiler in cross-compilation). I 
am sure autotools supports this host/target approach (but the terminology 
may differ).
