kernel_img-kern_device.o: In function `grub_device_iterate':
../kern/device.c:84: undefined reference to `__enable_execute_stack'

That's defined in libgcc so I add -lgcc to the link flags:

/usr/lib/libgcc.a(_enable_execute_stack.o): In function
`__enable_execute_stack':
_enable_execute_stack.c:(.text+0x40): undefined reference to `__sysctl'
_enable_execute_stack.c:(.text+0x6f): undefined reference to `mprotect'

Both of those symbols are defined in libc.a, so I included that, too.
Any ideas?

Bean's lnxboot.S patch fixed this.  Thanks Bean!

Correction:  grub2 builds correctly right out of the box.  Dunno why
I had problems the first time.  Black Magic!
