With UEFI you don't need bios_grub partition. You also don't nee the legacy_boot flag. But what you need is a FAT32 partiton where the GRUB's UEFI binary will be installed. You mount that partition at /boot/efi You should also set GRUB_PLATFORMS="efi-64" in make.conf and update world. After that run "grub2-install /dev/sda" (or whatever block device you use). Then you can verify that GRUB 2 is added into UEFI boot menu: run efibootmgr as root (it's from sys-boot/efibootmgr package).
