You should drop the -optdep here

As a side effect of finally removing the -optdep-f flag,

  (another relevant commit is  994d5e3cfc32cb624b63683205dd8fd876171d0c)

the code that strips -optdep from the filename, which was required to
make  -optdep-f -optdepfoo  work, also got removed. The fact that
-dep-makefile continued to strip -optdep was an accident in my view.
