That tarball is the result of the first (outer) 'make dist', which
likely was run in your development tree.  It was likely generated from
a tree which had many/most/all of the options selected, so that all
directories existed in the build tree.  No wonder it has everything
needed.  

(Even if the latest configure didn't have some options selected, your
tree may have had slightly stale makefiles left over from earlier
'configure's with different options, essentially leaving you with a
complete tree nonetheless.)

Obviously.  We know one 'make dist' succeeded, since it wouldn't have
created the '=build' directory otherwise.  It is the inner 'make
dist', the one inside the '=build' directory, that is failing.

Well, one reason is it's automake philosophy (or cussedness, if you
want it that way ;-).  Basically, you want the user of the
generated tarball to have all the privileges of a developer --
including the expectation that a 'make dist' in a default configured
build directory will generate a complete tarball with all features.

Another reason is that it is a great "debugging" feature.  It helps
you root out mistakes that you may have made w.r.t builddir, srcdir,
dist, nodist, BUILT_SOURCES and other issues.

It all boils down to this: the tarball generated by 'make dist' should
NOT depend on what flags you passed to 'configure' in the build tree
where you ran 'make dist' or 'make distcheck'.
