ld: Issue an error if group nested too deeply
If a linker script has a group nested too deeply by mistake, issue an
error instead of hanging forever without outputting any error message.
PR ld/33265
* ldlang.c (MAX_NESTED_GROUP_DEPTH): New.
(open_input_bfds): Add a pointer argument for the nested group
count. Increment the count before the while loop and decrement
it after the loop. Issue an error if the nested group count >=
MAX_NESTED_GROUP_DEPTH when processing input statement.
(lang_process): Update open_input_bfds calls.
(cmdline_emit_object_only_section): Likewise.
* testsuite/ld-scripts/libpr33265-1.a: New file.
* testsuite/ld-scripts/libpr33265-2.a: Likewise.
