yaboot is built with e2fslibs 1.41 explicitly.  Support for 64bit ext4
was added in 1.42.  Trying to build against the new version gives lots
of errors about missing things that libc provides, which is of course a
problem since yaboot does not provide an entire libc since it is a boot
loader and not an OS.

It would appear to be quite a lot of work to fix this.  It would seem a
better use of time to just say: If you want to use the new 64bit ext4
features and yaboot then you better have a seperate /boot that is NOT
64bit ext4.  That's probably not that much of an inconvinience.
Of course if ext4 is being created by default in 64bit mode these days
(I have no idea), then the installer may need to be taught to not do
that for whatever filesystem /boot is going in.
