I am currently investigating why those files are missing.
I may have an idea that I am currently testing.
The README.mknative lists a few steps. (Sorry I am working on a really
old version : 6.0 - haven't got around to update to latest sources yet,
this will be done once we see the kernel in a stable state)

The following files are generated by bootstrap-libgcc:
eco32-make bootstrap-libgcc
Creating files needed for libgcc by a native bootstrap build.
external/gpl3/gcc/lib/libgcc/arch/eco32.mk changed
external/gpl3/gcc/lib/crtstuff/arch/eco32.mk changed
external/gpl3/gcc/lib/libgcc/libgcov/arch/eco32/defs.mk changed
external/gpl3/gcc/lib/libgcc/libgcov/arch/eco32/gcov-iov.h changed

eco32-make is just a symlink in my PATH.
I am not sure if that are all files but I proceeded with the next step:

4. At top level, do
   "nbmake-MACHINE do-distrib-dirs obj includes MKGCC=no MKBINUTILS=no".

back in the src/

do-distrib-dris runs without problems.
obj on the other hand resutls in

obj ===> external/gpl3/gcc/lib/libgcc/libgcc
nbmake:
"/hdd/home/okarin/eco32/netbsd-on-eco32/usr/src/share/mk/bsd.files.mk"
line 110: Wrong number of words (1) in .for substitution list with 2 vars
nbmake: Fatal errors encountered -- cannot continue
nbmake: stopped in
/hdd/home/okarin/eco32/netbsd-on-eco32/usr/src/external/gpl3/gcc/lib/libgcc/libgcc

Now I tried that part again
eco32-make obj MKGCC=no MKBINUTILS=no -V BUILDSYMLINKS

There is no output whatsoever :(

My next step would be to follow the build process of bootstrap-libgcc
and see what it does.
(I tried that a couple of months ago but with no result).

For now I assume the mistake is on my side because other arches build well.

With best regards,
Jens
