You could always emigrate... :-)

Sorry:

   collect2: ld returned 1 exit status

The problem is that --enable-targets=all beings in all of the 32-bit 
targets, but sets the default target to bfd_elf32_i386_vec.  So it does 
not trigger the new code you added at the end of config.bfd.

I think that the question remains: Why is the 32-bit version of 
elfxx-sparc.c attempting to access 64-bit functions when support for 
64-bit sparcs is not enabled ?

Cheers
