+ maint.mk: avoid warnings about missing files

+ (_cfg_mk): Define, so it can be empty when cfg.mk does not exist.
+ (syntax-check-rules): Use $(_cfg_mk) to avoid a diagnostic about
+ nonexistent cfg.mk.
+ Suggestions from Simon Josefsson.

+
+ vc-list-files: avoid failure when /bin/sh is dash
+ * build-aux/vc-list-files: Avoid a shell portability problem with dash.
+ On some Debian based systems, /bin/sh is a symlink to dash, and running
+ this command would omit the "/" following each 'tests' prefix:
+ dash -x build-aux/vc-list-files -C . tests
+ That is because bash and dash work differently:
+ $ for i in bash dash; do $i -c 'a=odd; a=ok b=$a; echo '$i' $b'; done
+ bash ok
+ dash odd
