Typo in Make file + No UEFI boot

[bert003]

Line 541 has to change from if [ "$NONFREE" = true ]; then to if [ "$NONFREE" == true ]; then

Also, UEFI boot does not work. I have all the requirements installed and the ISO compiles successfully. I compared version 4 and version 5 and the only differences seem to be in the grub EFI files. They are much larger in size.

Any feedback?
