Subject: [PATCH] ledit: fix broken executable

Prior to this change ledit failed with a 127 exit code:

    $ ledit
    no bytecode file specified
    $ echo hello | ledit cat
    the file 'cat' has not the right magic number: expected Caml1999X036

Upstream builds ledit with `ocamlc -custom`, which attaches the program
to the end of the executable. Stripping drops it again.
With dontStrip the program stays in place:

    $ echo hello | ledit cat
    hello
    hello
