I should have noticed/noted that despite the link being broken in

/mnt/build/xgcc-4.1/sparc-sun-solaris2.9/sparc-sun-solaris2.9/usr/lib/

the /usr/lib/libc.so it was trying instead is of course the same one 
that should have been in the tree. So even after sorting out the library 
structure it was the same error. I tried the elflink.c patch I mentioned 
but still had the same problem. So either it is the 2.11/2.9 
incompatibility you mentioned or else the wrong architecture? These 
libraries, being from my host, are Intel. I think that last command is 
trying to make something to do with libgcc, which presumably should be 
cross-compiled targetting Sparc. So maybe I need Sparc libs in the 
aforementioned directory? Sorry, there are so many stages and 
directories I'm pretty confused now.

As in my previous post, it would be tricky to get the libs from the 
target machine. Is there any hope that compiling the earliest 
OpenSolaris ones from source would work somehow? I'm thinking maybe the 
process needs to do bootstrapping in some way like crosstools does.
