[FYI] {master} Prefer `$(am__cd)' to plain `cd' in our Makefiles.

[Stefano Lattarini]

I pushed the attached patch (pre-approved by Ralf) to master.

Regards,
   Stefano

-*-*-

Prefer `$(am__cd)' to plain `cd' in our Makefiles.

* Makefile.am (recheck, dist-hook, git-dist, path-check, fetch)
(release-stats): Use `$(am__cd)' rather than plain `cd'.
* tests/Makefile.am ($(srcdir)/parallel-tests.am): Likewise.
