Subject: [PATCH 32/46] util/mkimage: Use grub_host_to_target32() instead of
grub_cpu_to_le32()
The latter doesn't take into account the target image endianness. There is
a grub_cpu_to_le32_compile_time() but no compile time variant for function
grub_host_to_target32(). So, let's keep using the other one for this case.
