On a system that dual boots Linux and Windows 10, the latest grub-efi 
gives this error:

error: symbol 'grub_efi_find_last_device_path' not found

when attempting to boot Windows 10 after an update-grub is performed.  
Linux will boot correctly;  however,  an attempt to boot Windows 10 will 
give this error and say "press any key..." and bring one back to the OS 
menu.

There is a workaround, which is to downgrade back to 2.02~beta2-32, and 
Windows will boot correctly.
