Well, the filename follows a common scheme across Debian's grub and debian-cd
packages and it naturally I would have to add some extra logic to work around
a limitation in Loongson's firmware which I would like to avoid.
The Loongson machines are the first UEFI systems that have shown this limitation,
so I would rather have Loongson fix that limitation than Debian have to implement
a workaround for something that works just fine on every other UEFI system.
