Handle -o w/ and w/o $EXEEXT during manifest embedding

[Peter Rosin]

Hi!

During my exercise with libsndfile I found a problem with
the manifest embedding code. $output may or may not contain
the trailing $EXEEXT, so the code in $postlink_cmds has
to handle both cases (or some c14n has to be added to ltmain).

So, here is a patch to address that. Ok to push to the
pr-msvc-support branch?

Cheers,
Peter

        [ cygwin, mingw, cegcc ] <cl*>: @OUTPUT@ may or may not
        include a trailing $EXEEXT. If mt fails, make sure libtool
        exits with an error.
        (_LT_LANG_CXX_CONFIG): Likewise.
