Subject: BUILD: Use split-dwarf debug symbol files by default, when available

This should improve linker time as well as reduce the size of the
built binaries (though this does not affect runtime memory usage
since the debug segments are not loaded into memory except by a
debugger) whilst still giving debug information.
