[Bug fortran/34227] New: initialized symbol in common: Better error message

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

character(len=3) :: emname(nmin)=(/'bar','baz'/)
 common/nmstr/emname
end

currently gfortran prints:

   Error: Previously initialized symbol 'emname' in COMMON block 'nmstr' at (1)

If find the error message of NAG f95 better, which mentions that BLOCK DATA can
be used:

   Error: EMNAME has been initialised - can only be COMMON in BLOCK DATA
