Thanks a lot for this hint. I indeed had not patched binutils. Doing so solved
a lot of problems. However, the gcc build still does not go through completely.
It stops in one avr subdir:
Running configure in multilib subdir avrtiny10
pwd: /usr/src/avr/avrgcc/avr
mkdir avrtiny10
configure: creating cache ./config.cache

checking for suffix of object files... configure: error: in
`/usr/src/avr/avrgcc/avr/avrtiny10/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1
make: *** [all] Error 2
When I move avrtiny10 away
mv avrtiny10 avrtiny10_
the gcc build succeeds. But this gets me into trouble when building avr-libc!
:-( So I guess I have to figure out what the problem is with this avrtiny10
subdir! The config.log says
...

mandir='${datarootdir}/man'
oldincludedir='/usr/include'
pdfdir='${docdir}'

sbindir='${exec_prefix}/sbin'
set_have_cc_tls=''
set_use_emutls=''
sharedstatedir='${prefix}/com'
slibdir='$(exec_prefix)/$(host_noncanonical)/lib'
sysconfdir='${prefix}/etc'
target_alias='avr'
target_subdir='avr'

vis_hide=''

I have no idea what this means and how this can be fixed. I applied all 20 gcc
patches one after the other and all went through without error messages (see
below). Still the tree does not build. I am rather clueless here! :-(
Hints still greatly appreciated!!
Thanks a lot,
Andreas
