In fact, the problem is with libtool. Some configure.in script use 
libtool and libtool scripts does not recognized the target x86_64. A 
simple "libtoolize --force" can be a solution. However, I played with a 
number of spells and some problems arise :

jpeg : this package contains a configure script, but not the 
configure.in or configure.ac, so it cannot be updated.

- some spells used a lot of m4 macros and most files where missing on 
the machines I was using. (Maybe since those spells were not compiled).

bin86 : this spells use ugly code that needs to be patched to work on 
x86_64.

and so on ... thus, from all those problems, I think we would need to 
check each and every spell.... and give up. I will however publish my 
bi-arch sorcery scripts on my web page.
