This did look fishy (going from $srcdir/.. to $builddir) and is not
correct :)

srcdir is the current source dir
builddir is the current build dir

both of those variable represent where the current directory is, in a
recursive setup this means inside tests/.

top_builddir/top_srcdir can be used to represent the topmost directory
in each case.

This should be either:
  - $(top_builddir)/version.h or
  - $(builddir)/../version.h

It happens to work because it's evaluated to "-include "./version.h",
and top_builddir is included by automake's default include search
paths.

DEFAULT_INCLUDES = -I. -I$(srcdir) -I$(top_builddir)
