exim: allow using a custom configuration file
exim has lots of options configurable before the build process. It's not useful to have all of them exposed in Buildroot, yet users may need to tweak them. Allow the user to pass an entire configuration file to make exim totally reconfigurable without bloating the Buildroot menus. [Thomas: remove "for exim" from Config.in options prompts.] Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
