But the whole idea was to let configure generate the makefiles in a new
directory next to blender, right ?

Nah, even if you turned this around 'let the configure system generate
Makefile.auto' it would not make sense as it still writes in the source
tree.

As it is now make starts complaining when you don't set the
NANBLENDERHOME and MAKEFLAGS. When we simply define NANBLENDERHOME in
every Makefile (as a relative path), and change the 'include
nan_compile.mk' etc. to 'include ../nan_compile.mk' etc. then we're set.
