grub-2.04-x86_64-3: 13 times uncompressed package size compared to -2

I just noticed that the uncompressed package size of grub grew from around 75 MB with grub-2.04-x86_64-2 to around 973M with grub-2.04-x86_64-3. The grub version did obviously not change and the only change in the grub.SlackBuild is the BUILD number.

The difference comes from the img files in /usr/lib64/grub/i386-pc/.

Background: I just tried to update a system which only has a small SD card and the upgradepkg ran out of disk space because i did not expect such an increase. :(
