This looks like grub legacy patched to support EFI (unless this line
is there by mistake). Upstream grub legacy never supported EFI as far
as I know, so unless someone is familiar with it, your best bet is to
contact patch author.

If I am wrong, please tell grub version (but this line is unlikely
from grub2 grub.cfg either).
