Masahiro Yamada a8b0f9b685 build: define CPU only when arch/${ARCH}/cpu/${CPU} exists ... The directory arch/${ARCH}/cpu/${CPU} does not exist in avr32, blackfin, microblaze, nios2, openrisc, sandbox, x86. These architectures have only one CPU type. Defining CPU should not be required for such architectures. This commit allows cpu field (= the 3rd field of boards.cfg) to be kept blank.
