The new dg test for stabs support quite reasonably expects an error if there is
no support. PTX was silently ignoring debug info requests. stabs is never
gonna work though, so be noisy for that.
also noticed another place I should be calling nvptx_assemble_decl_end

* config/nvptx/nvptx.c (nvptx_option_override): Emit sorry for
stabs debug.
(nvptx_assemble_undefined_decl): Use nvptx_assemble_decl_end.
