Probably my configuration will not match Gunther's exactly but, to test 
this, I've modified the $prefix/bin directory where I have an 
arm-none-elf installed toolchain.  I added `as' which is the host tool, 
and removed `arm-none-elf-as'.  I then configured the toplevel and gcc 
with --prefix=~/testprefix, and every variable pointing to an 
AS_FOR_TARGET is pointing to the non-existent (but correct) 
arm-none-elf-as.  Inside the gcc directory it even pointed to the 
$prefix/$target/bin/as.

Gunther, you did not mention really what your build/host/targets are.  
Could you send me privately the generated gcc/Makefile?
