Before this commit, u-boot and vboot_reference are inter-dependent on
each other; the former needs to be linked with the latter, and the
latter needs the compiler flags of the former to be built properly.
This commit hard-code u-boot's compiler flags into Makefile, and thus
removes the inter-dependency. Note that this is just a temporarily
measure before we get the compiler flags right.
