Porting NetBSD to Eco32

[Jens Mehler <jens.mehler%mni.thm.de@localhost>]

Hi everyone !

Currently a small team is porting NetBSD to a new processor called
eco32. It's an educational 32bit RISC processor for which I had already
ported GCC and Binutils.

Currently we are working with NetBSD 6.0.1:
It was the lastest stable release as we started this project about one
year ago - give and take half a year :)
I know about the securety issues with this version and we are planning
on updating as soon as we got it working (somehow beeing able to boot
that stuff into single user mode).
Anyway.

While being able to cross-build the kernel and loading binaries
(self-written) instead of the default init, I started to work on the
userland part.
I took a pretty much stupid approach:
./build.sh -M ../obj/ -T ../tools/ -D ../dest/ -R ../release/ -u -U -m
eco32 distribution

After fixing up the missing file errors like missing libc it spits:

obj ===> lib/../external/gpl3/gcc/lib/crtstuff
nbmake:
"/hdd/home/okarin/eco32/netbsd-on-eco32/usr/src/external/gpl3/gcc/lib/crtstuff/Makefile"
line 33: Cannot open
/hdd/home/okarin/eco32/netbsd-on-eco32/usr/src/external/gpl3/gcc/lib/crtstuff/arch/eco32.mk

So I read around the mailing lists an came cross the src/tools directory.
In the gcc directoy I found a README :) - happy as I was I started that
procedure:

It resulted in utter failure: step 2 fails :(
I think I am missing a step between before the native GCC part.

Any pointers would be nice :)

With best regards,
