There doesn't seem to be anything wrong here.

So, let me get this right. Although $(REPOSITORY)/$(PACKAGE)/include/var_cache.h
points to the correct file, somehow you are getting the mips32 version
of the file instead? That does not make any sense.

What does the $(PACKAGE) variable contain? It should be
"hal/mips/mips64/current".

Are you configuring in a fresh directory? Trying to move an existing
configuration from one target to another sometimes leaves remnants of
the old configuration around.

Try using ecosconfig. The following commands are what I used to test with:

$ mkdir atlas5kc.ram.kernel
$ cd atlas5kc.ram.kernel
$ ecosconfig new atlas_mips64_5kc kernel
$ ecosconfig tree
$ make
