Since there is already the __divtf3@GCC_3.0 compatibility alias in
libgcc we need to attach an explicit symbol version to the real __divtf3
in order to get it exported. This fixes the unversioned reference in
libgfortran.so, and fixes the failure of gfortran.dg/erf_3.F90. Tested
on ia64-suse-linux.
