Replace includes of build.h with version.h

As build.h is an auto-generated file it was necessary to add it as
an explicit prerequisite in the Makefiles. When this was forgotten
abuild would sometimes fail with following error:

   fatal error: build.h: No such file or directory

Fix this error by compiling version.c into all stages.
