This breaks tools-only_defconfig in non-trivial ways due to calling
bootm_decomp_image() which is not normally available to it.  Can you
please update things (it may just end up being common/Makefile that
needs tweaking) so that tools-only builds?  I'll then take a look and
make sure we don't also see unexpected size growth elsewhere.  Thanks!
