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:
PR debug/97060
* gcc.dg/debug/dwarf2/pr97060.c: New test.
