Thanks, as we discussed in private the toolchain has now been updated,
even though I've been notified by various sources that it is broken
for some AVR architectures. Since I haven't been able to solve the
problem quickly, I'm asking for some help on the list. So, here's an
explanation of what I found out until now.

What's happening: avr-ld, for some reason, doesn't descend into
/usr/avr/lib/ subdirectories while searching for object files, so it
doesn't find arch-specific linker files. I've found an old bug report
that oulines the same problem, even though with no solution posted:
http://savannah.nongnu.org/bugs/?22539

A (temporary and very ugly) workaround, for those who work with only
one architecture, is linking files in, for example, /usr/avr/lib/avr4/
to /usr/avr/lib/, paying attention to backup files by the same name
(libm.a, libc.a...).

In the meantime I'm trying hard to solve the issue, but I can't really
find where the problem lies, so if anybody has any knowledge of
toolchain-building and has suggestions to share, please write  :)

Thanks,
Corrado
