From 246976987ab3541336450030876b8650e786c581 Mon Sep 17 00:00:00 2001
From: Jeremy Harris <jgh146exb@wizmail.org>

Subject: [PATCH] Fix build for update on library component.

When, eg, the smtp transport is changed the transports library must be rebuilt.
Fix the main makefile to not assume that the date on the library .a is sufficient,
but always call the library subdir makefiles.
