+Fix parallel build issue
+
+The config.h header file must be created before being used to build
+source files that include it, especially version.c. In order for this
+to happen even in highly-parallel builds, we add a dependency of all
+object files on config.h, in order to ensure it gets generated before
+make attempts to build the object files.
