The make macro to check if the binary exceeds the board size limit is taken straight from the root Makefile.
Without this and e.g. enabled EFI Vybrid fails booting as the regular size limit check does not take the final u-boot.imx binary size into account which is bigger due to alignment as well as IMX header stuff.

Changes in v2: - Dropped CONFIG_CMDLINE_EDITING and SPI support to save another 8 Kb of precious space. Alternatively, I may have to drop full EFI support which costs more than 36 Kb.
