Please submit testcases so that we can make sure ld is doing the
right thing.

The problem is the current ld does the wrong thing. For Franz's
testcase, it generates

00000288 g    DF .text  0000000a (VEROLD)     divdi3

instead of intended

000002d8 g    DF .text  0000000a (VEROLD)     divdi3
000002e4 g    DF .text  0000000a  VERNEW      divdi3

without any warnings.
