    dwarf2: Set DW_AT_declaration for undefined fns [PR97060]

    If DECL_INITIAL isn't set, we can't emit anything about the body of the
    function, so add the declaration attribute.

    gcc/ChangeLog:

            PR debug/97060
            * dwarf2out.c (gen_subprogram_die): It's a declaration
            if DECL_INITIAL isn't set.

    gcc/testsuite/ChangeLog:

            * gcc.dg/debug/dwarf2/pr97060.c: New test.
