Update check for working assembler --gdwarf-4 option
Rename HAVE_AS_WORKING_DWARF_4_FLAG to HAVE_AS_WORKING_DWARF_N_FLAG
Don't set HAVE_AS_WORKING_DWARF_N_FLAG if --gdwarf-5/--gdwarf-4 generate
an extra assembly input file in debug info from compiler generated
.debug_line or fail with the APP marker:
https://sourceware.org/bugzilla/show_bug.cgi?id=25878
https://sourceware.org/bugzilla/show_bug.cgi?id=26740
https://sourceware.org/bugzilla/show_bug.cgi?id=26778
Also replace success with dwarf4_success in the 32-bit --gdwarf-4 check.
PR bootstrap/97451
* configure.ac (HAVE_AS_WORKING_DWARF_4_FLAG): Renamed to ...
(HAVE_AS_WORKING_DWARF_N_FLAG): This. Don't define if there is
an extra assembly input file in debug info. Replace success
with dwarf4_success in the 32-bit --gdwarf-4 check.
* dwarf2out.c (asm_outputs_debug_line_str): Check
HAVE_AS_WORKING_DWARF_N_FLAG instead of
HAVE_AS_WORKING_DWARF_4_FLAG.
* gcc.c (ASM_DEBUG_SPEC): Likewise.
(ASM_DEBUG_OPTION_SPEC): Likewise.
* config.in: Regenerated.
* configure: Likewise.
