Hm, I think it's because we're not building the firmware binaries until modules_install time, and only _then_ do we want to build the ihex2fw tool.
If you run 'make modules_install INSTALL_MOD_PATH=/tmp/foo' on the x86_64 host first, does that fix it?
I was planning to build the firmware binaries as part of 'make modules' anyway, because Rafael had related problems (not being able to write to the NFS-exported kernel tree at all).
