This works for me with GCC 4.4.0 20081011 + GAS 2.18.92 + Sun ld on Solaris 9.

I've just tried again on current mainline (trunk revision 142371) on
Solaris 11 (snv_103), both with Sun as and GNU as 2.19, and get the same
error in both cases.

The compilers were configured as follows:

I'm currently running bootstraps on Solaris 10 (both with Sun as and GNU as
2.19) to verify if this makes a difference.

It doesn't: I get exactly the same error.

But these are not 64-bit compilers, see the target triplet.  You need to pass
--build=sparc64-sun-solaris2.11 and start with a 64-bit compiler.

I fear you're right: it occured to me that the GCC 3.4.3 I started with
didn't have proper multilib support.  I had started with gcc3.4.3 -m64
(which would have been a 64-bit compiler), but forgot to specify the
correct target triplet, though I'm pretty sure I did so when I first
reported the bug.

I've now used a 32-bit gcc 4.4.0 with -m64 as bootstrap compiler and
specified --build=sparcv9-sun-solaris2.10.  This time, the bootstrap
finished, so this has been pilot error ;-(

Thanks for investigating on your side.
