Well, you could start with an objdump and compare the exposed symbols, this
would show.

One thing is libio, we will get that now (*sigh* some hard bugs in the way,
though, difficult to debug.  It works in a chroot, but not at boot time).

Then pthreads would be nice.

Cleaning up the remaining differences.

And then we need to change the .note.ABI-tag section to match the GNU/Linux
one.
