The rules in the makefiles cause config.status to only update the file
that triggered the rule.  E.g.,

GNUmakefile: GNUmakefile.in $(top_builddir)/config.status
    CONFIG_FILES=$@ CONFIG_HEADERS= ./config.status

(Yes, this interface is incredibly stupid.)

Ok, now I see it.  I guess we'll have to go back to forcing a touch of
config.h after config.status runs in order to get this to work properly.
