I've seen these kind of errors always when linking a file into a shared 
library that wasn't compiled with the -fPIC flag (with good candidates 
always being libgcc.a and libstdc++.a). I would first make sure that all .o 
files are compiled with this flag and then examine the line which links 
together (-Wl,--verbose might be a useful flag for gcc.)

That seems to confuse me a bit. The error might well be in the gcc setup, 
but binutils shouldn't affect the behaviour. At least we've got vanilla GNU 
binutils 2.10.1 running here without any problems (NetBSD sparc 1.5). 

HTH anyway
