Update README.md to recommend passing CROSS_COMPILE via env

Building u-boot should pass CROSS_COMPILE via the environment
rather than a make variable; some ARM64 boards require parts of
the bootloader to be built w/ 32-bit toolchains, setting
CROSS_COMPILE via a make variable prevents that override from
working.
