While looking through dwarf2out.c I came across this if expression where
supposedly in case DWARF before 5 is used the 128 LEB encoding is used.
This of course cannot be the case. There isn't really a deeper problem
since the entire block is guarded by a test for at least DWARF 5.
I propose the following patch.

* dwarf2out.c (output_file_names): Avoid double testing for
dwarf_version >= 5.
