Fix build failure on Windows with older binutils
This is the build failure on Windows with binutils for which GNU as accepts
the --gdwarf-5 switch but GNU ld generates broken binaries with DWARF 5.
We already have the HAVE_LD_BROKEN_PE_DWARF5 kludge to disable DWARF 5 in
this case but it only tames the DWARF version in the compiler, so the
driver still passes --gdwarf-5 when invoked on an assembly file with -g.

PR target/101377
* gcc.c (ASM_DEBUG_DWARF_OPTION): Set again to --gdwarf2 in
the case where HAVE_AS_WORKING_DWARF_N_FLAG is not defined
and HAVE_LD_BROKEN_PE_DWARF5 is defined.
