Simplicity.  Setting the default to 4 broke lots of tests (in the assembler
and binutils directories).  Setting the default to 3 does not break the tests.

Plus, and this is very minor, version 4 DWARF line number tables are 
actually bigger than version 3 tables, because of the addition of the
Maximum Ops Per Instruction field in the table header.

But if there is a consensus that version 4 is the way to go, then I can
change the default and update the tests.

Cheers
