[yocto] Fail to build core-image-minimal when MACHINE=genericx86-64

Thu Oct 31 15:48:38 PDT 2013

With the help of a friend, have confirmed that 'core-image-minimal' 
cannot be built with Ubuntu 13.10 64-bit when MACHINE=genericx86-64. 
Attempted the build on a different machine in a different city, same 
results (failure to build).

Confirmed that 'core-image-minimal' can be successfully built under an 
lxc and a chroot running Debian Wheezy, on Ubuntu 13.10 64-bit, with 
MACHINE=genericx86-64.

Filed bug 5440 on Yocto Bugzilla.
