And what is your partitioning and fstab?
gummiboot wants all inside the ESP and this mounted at /boot:
# grep boot /etc/fstab
UUID=E004-1D89 /boot vfat auto 1 2
The gentoo GRUB2 wiki tells me to mount that at /boot/efi ...
And grub2 fails to install now (with or without --boot-directory):
# grub2-install --target=x86_64-efi --boot-directory=/boot
Installing for x86_64-efi platform.
grub2-install: error: cannot find EFI directory.
I am *sure* that I have some crap in my ESP ... from my initial
fiddling back then.
See the current tree:

Note: the stuff in efi/boot configured grub2 until a few days ago.

And current efibootmgr:
# efibootmgr
** Warning ** : Boot000a is not EFI 1.10 compliant (lowercase hex in name)
** Warning ** : please recreate these using efibootmgr to remove this
warning.
BootCurrent: 0008

Boot0006 Hard Drive
Boot0008* UEFI: Samsung SSD 840 EVO 250GB
Boot0009* ATAPI CD-ROM Drive
Boot000a Unknown Device
I would appreciate any help to clean that up and get both gummiboot
and GRUB2 installed as parallel UEFI applications.
Currently gummiboot works very well!
Thanks,
Stefan
