0.8.5.26:
	Record filesystem information during the build in debug information
	relative to SYS, not to /home/kevin/sbcl or equivalent.
	... change to core code: tiny if ugly;
	... change to warm load: only to refer to files as lpns rather
		than physical namestrings;
	... change to vanilla-modules: tiny;
	... change to asdf modules: well, erm, less tiny.  I'm not pleased
		by the need to duplicate similar logic in every .asd, but
		I think it's a similar symptom to the duplication of the
		TEST-OP logic in many of them: the coupling between asdf
		and the rest of the system is slightly wrong.

	(At startup, SYS by default has translations that refer back to
	the build-time values; distributors may wish to alter this for
	their binaries, for instance by setting translations to
	distribution-known values when dumping any final image)
