CPU_TYPE "xxx" doesn't correspond to a known type

[Philip Prindeville]

Yeah, it's intentional.  It was meant to be a sentinel for bitrot.

If you look at the line following the changes:

  DEFAULT_CFLAGS=$(strip $(CPU_CFLAGS) $(CPU_CFLAGS_$(CPU_TYPE)) $(CPU_CFLAGS_$(CPU_SUBTYPE)))

You don't want to have an empty expansion of CPU_CLFAGS_* as these are usually important platform-specific values that cause the correct instruction set to be emitted for the particulars of the CPU type.

See the preceding lines for -march and -mcpu values per platform.
