elf.h: Use TARGET_OS_CPP_BUILTINS rather than SUBTARGET_SPEC.

config/h8300:
	* elf.h: Use TARGET_OS_CPP_BUILTINS rather than
	SUBTARGET_SPEC.
	* rtems.h: Similarly.
	* h8300.h (CPP_PREDEFINES, CPP_SPEC, SUBTARGET_CPP_SPEC,
	EXTRA_SPECS, SUBTARGET_EXTRA_SPECS): Remove.
	(TARGET_CPU_CPP_BUILTINS): Use.
