No problem, I was only worried because your email bounced.
Is anciens.enib.fr gone for good?

sid also has "gcc-4.4 (Debian 4.4.6-14) 4.4.6" but it also does not
support -all-static (which makes sense because it is a libtool option).

A few lines from my build log, maybe you can check what is different
for you:

The difference for gold is that libtool is not used.  The easiest fix would be
to patch the gold Makefile to filter out the -all-static.  Or maybe gold
can be libtoolized. But first I would be interested to understand why this builds for you.
