'NEED_CPU_H' guard target-specific code; it is defined by meson
altogether with the 'CONFIG_TARGET' definition. Since the latter
name is more meaningful, directly use it.

This feels to me like it's overloading the meaning of CONFIG_TARGET,
which at the moment is "the string which names the header file
with target-specific config definitions". I think I'd rather
we just renamed NEED_CPU_H to something a bit clearer, like
perhaps COMPILING_PER_TARGET (better suggestions welcome).

thanks
