I see. Each of the configure runs in Debian buildd logs uses exactly
one combination of --with-platform and --target.
But the configure runs all happen before the first compilation activity.
So i would not consider this a duplication but rather combination of
variations for different firmwares. Of course, the compilation job gets
bigger with each variation that gets added.

Small notebooks and tablets without CSM, iirc from lurking at mailing lists.

Vladimir Serbinenko contributed HFS+ production code to libisofs, so that
xorriso can write HFS+ metadata, bless /System/Library/CoreServices/boot.efi,
and produce an Apple Partition Map.
The source code in util/grub-mkrescue.c shows that HFS+ is created
if (source_dirs[GRUB_INSTALL_PLATFORM_I386_EFI]
|| source_dirs[GRUB_INSTALL_PLATFORM_X86_64_EFI]
|| source_dirs[GRUB_INSTALL_PLATFORM_POWERPC_IEEE1275])
and that blessing happens
if (source_dirs[GRUB_INSTALL_PLATFORM_I386_EFI]
|| source_dirs[GRUB_INSTALL_PLATFORM_X86_64_EFI])
The file img_mac="boot.efi" gets composed by grub-mkrescue.c from the EFI
startup programs img32="bootia32.efi" and/or img64="bootx64.efi":
if (source_dirs[GRUB_INSTALL_PLATFORM_I386_EFI]
&& source_dirs[GRUB_INSTALL_PLATFORM_X86_64_EFI])
grub_util_glue_efi (img32, img64, img_mac);
else if (source_dirs[GRUB_INSTALL_PLATFORM_X86_64_EFI])
grub_install_copy_file (img64, img_mac, 1);
else if (source_dirs[GRUB_INSTALL_PLATFORM_I386_EFI])
grub_install_copy_file (img32, img_mac, 1);
For Macs which need HFS rather than HFS+, you will have to resort to
mkisofs or genisoimage. Debian does this for its "powerpc" ISOs.
Have a nice day :)
