[PATCH] Documentation: boards: k3: fix typo in build instructions

[Ahmad Fatoum]

The file starts with defining and exporting CROSS_COMPILE_32 and
CROSS_COMPILE_64 environment variables, which are used for building the
individual components of the boot chain.

CROSS_COMPILE should be set to the $variable, so it expands correctly.
