	[bug #17127]
	* Makeconf (clean): Don't remove `*.*_d' files.
	(%.sdefsi): Add `%.sdefs.d' to the target list.  Create these files by
	specifying `-MD' as a flag for CPP and mangle the output as needed.
	Include these `*.sdefs.d' files instead of `*.migs_d' and `*.migsh_d'
	files.
	(%.udefsi): Likewise for `%.udefs.d' / `*.migu_d' and `*.miguh_d'.
	(%.migs_d, %.migu_d, %.migsh_d, %.miguh_d): Remove targets.
