The efm32 platform does not provide a zreladdr-y line its Makefile.boot,
so we always have to use CONFIG_AUTO_ZRELADDR in order to successfully
build and link a zImage.

I wonder why you need to AUTO_ZRELADDR (which is there to guess
zreladdr) while efm32 doesn't have an MMU and so there is nothing to
guess. So I think this patch fixes a build problem, but it's not a good
change.

It is required in order to build a compressed zImage file. You mentioned
before that your system does not have enough RAM to support this, but
the compile-time option exists, and there is no dependency on MMU support
for it, nor should there be.
