[patch] Downgrade DWARF_VERSION_DEFAULT to 3 for VxWorks >= 7

[Olivier Hainque via Gcc-patches]

Hello,

Using 4 as the DWARF_VERSION_DEFAULT value for VxWorks observably
still hangs recent system debuggers on tbreak for some contructs,
and downgrading to 3 improves the situation.

Committing to mainline shortly.

Cheers,

Olivier
