No, this is not provided by LFS book. The hints are written by fans.

I'm using efivars 31. I just gone to efivars homepage and got the
latest version when I was building LFS.

Yes, my efivars-31 links to shared libpopt. Static libpopt is not
necessary and we should use BLFS guide.

grub.cfg must be customized. I always build GRUB with devmapper
support, and use PARTUUID to find partitions.
(Or my system won't boot with an USB stick plugged in).
The only thing we can learn from the example is
insmod efi_gop
insmod efi_uga
insmod font
if loadfont ... then
... ...
fi
If you are using a seperated /boot partition (LFS book 2.4.1.4),
you should "set root=(</boot partition>)" and use "/vmlinuz"
in grub.cfg. If not, "set root=(<root partition>) and use
"/boot/vmlinuz".
