Right, sparc-elf and sparc-rtems were hijacking sol2-ci.asm and sol2-cn.asm, 
which are supposed to be Solaris-specific.  Now the RTEMS folks complained 
about the removal and I accepted to backpedal for sparc-rtems:
  http://gcc.gnu.org/ml/gcc-patches/2011-01/msg00530.html
They never applied the patch, though.

The funny thing is that neither sparc64-elf nor sparc64-rtems build them.
But they are very likely little used targets.

I guess the best solution to clean up the mess at this point is to backpedal 
entirely and build them (again) for sparc*-elf and sparc*-rtems.  I'll do the 
change for the upcoming 4.6.1 release.

Thanks for bringing this to my attention.
