Hi,

this patch fixes a recently discovered name-clash in gfc_build_class_symbol.

Fortunately it is quite easy to fix: just make sure that the class names of target
classes end with "_t", and target array classes end with "[0-9]t".
This trick makes all names unique again.

I hope it is not too late, and this can still go into 4.9.0.

Boot-Strapped without any regressions on x86_64-unknown-linux-gnu.

Ok for trunk?

Thanks
Bernd.
