[PATCH] gcn: Fix a warning

[Jakub Jelinek]

Hi!

I see
../../gcc/config/gcn/gcn.cc: In function ‘void 
gcn_hsa_declare_function_name(FILE*, const char*, tree)’:
../../gcc/config/gcn/gcn.cc:6568:67: warning: unused parameter ‘decl’ 
[-Wunused-parameter]
 6568 | gcn_hsa_declare_function_name (FILE *file, const char *name, tree decl)
      |                                                              ~~~~~^~~~
warning presumably since r14-6945-gc659dd8bfb55e02a1b97407c1c28f7a0e8f7f09b
Previously, the argument was anonymous, but now it is passed to a macro
which ignores it, so I think we should go with ATTRIBUTE_UNUSED.

Ok for trunk?
