Subject: Add definitions that let me factor the wget rule while still letting
X-Git-Tag: CPPI-1_9~41
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=c8f712ac705da87569468e1d57d1124f4800071c;p=thirdparty%2Fcoreutils.git

Add definitions that let me factor the wget rule while still letting
me accommodate the fact that these files reside in several different
directories and come from different places.

(wget-files): Define.
(get-targets, *-local_dir, *-url_prefix): Likewise.
(target, url, local_file): Convenience variables.
($(get-targets)): The factored rule.
