aix: default to DWARF 4.
GCC now defaults to DWARF 5. AIX only supports DWARF 4 (3.5).
This patch overrides the default DWARF version to 4 unless explicitly
stated.
gcc/ChangeLog:
* config/rs6000/aix71.h (SUBTARGET_OVERRIDE_OPTIONS): Override
dwarf_version to 4.
* config/rs6000/aix72.h (SUBTARGET_OVERRIDE_OPTIONS): Same.
