 You're using a bare-metal target, so it looks to me like you need to 
configure for the `x86_64-elf' target or suchlike; this is what the `elf' 
"OS" is for (with some exceptions).  If there's none currently supported 
for the x86_64 architecture, then you may have to fiddle with the sources 
and/or build scriptery a bit.  Given the similarity of the architectures 
using `i386-elf' as a reference might be a good starting point.
