.d (.MMS in the VMS world) files with just dependencies are built from
exactly the same conditions as the object files. Therefore, the rules
for them can be built at the same time as the rules for the
corresponding object files.
This removes the requirement for a src2dep function in the build file
templates, and for common.tmpl to call it. In the end, the existence
of depend files is entirely up to the build file.

There was a catch 22, where 'make depend' directly after configuring
in an otherwise pristine build tree would fail because buildinf.h
didn't exist yet.
This change has the depend building targets depend on the same other
targets as the object file building targets, so the generation of
buildinf.h and similar files would kick in during 'make depend'.

common.tmpl will be used together with the template build file, and is
the engine that connects the information gathered from all the
build.info files with making the build file itself.
This file expects there to be a template section in the build file
template that defines a number perl functions designed to return
strings with appropriate lines for the build system at hand. The
exact functions, what they can expect as arguments and what output
they're expected to produce is documented in Configurations/README.
