Changing PATH in the wrappers

[Akim Demaille]

I sent a couple of days ago a bug report.  Here is the patch I'm
suggesting.  I'm also asking for writing permission on Libtool CVS, so
that I can apply my patches.  Of course, I will wait for approvals.  I
also plan to improve Autoconf 2.55 compatibility.

Please, install this patch, as without it GNU M4 fails to distcheck.

(I have failures, but they are Fortran related.  I'll have a look at it).

        * ltmain.in: Do not change the PATH in the wrappers: let them
        launch the real binary using its path.
