Drop that blank line and invert the order.  Say "New macro".

Write it like this:

	* sysdeps/unix/sysv/linux/x86_64/dl-cache.h:
	Don't include <sysdeps/unix/sysv/linux/sparc/dl-cache.h>.
	(add_system_dir): New macro.

While you're here, it seems appropriate to lift the e_machine sanity check
above the if and make it accept only EM_{386,X86_64} (unconditionally)
and EM_IA_64 (only for ELFCLASS64).


Thanks,
