From there I'd search in Guix for the code for bootloader-configuration.
I would also start by looking at grub's configure.ac to see what options
exist:
# Specify the platform (such as firmware).
AC_ARG_WITH([platform],
AS_HELP_STRING([--with-platform=PLATFORM],
[select the host platform [[guessed]]]))
# Guess the platform if not specified.
if test "x$with_platform" = x; then
case "$target_cpu"-"$target_vendor" in
i386-apple) platform=efi ;;
i386-*) platform=pc ;;
x86_64-apple) platform=efi ;;
x86_64-*) platform=pc ;;
powerpc-*) platform=ieee1275 ;;

I'm pretty sure grub-efi builds for ppc64le, but it looks like you've
selected grub above.
