pkglib_PROGRAMS is now rejected

[Jim Meyering]

I normally use automake built from the head of "master",
but not long ago, it started failing like this:

    src/Makefile.am:141: error: `pkglibdir' is not a legitimate directory \
      for `PROGRAMS'

That variable determines where we install libstdbuf.so.

One possibility is to change src/Makefile.am as below,
but that would mean moving libstdbuf.so from
$prefix/lib/coreutils/ to
$prefix/libexec/coreutils/
and adjusting stdbuf.c, and causing distros to adjust.

There's probably a less invasive change...
