weechat 1.1-rc1 devel

Devel version, returned the ` gettext ` dep that was removed in #18722 but is now functional again, prunes the redundant ` -DENABLE_GTK=OFF ` option as it’s not a valid option anymore and reformats the args.
Aye it is. There's a curl link and the curl on older OS X versions is getting a little outdated, so it's useful to have the option to go newer in places, so I thought I'd push it in. I guess we could chuck in a ` with-brewed-curl ` option.
