fix coreutils' "make distcheck": remove AC_CONFIG_LIBOBJ_DIR(lib)

[Jim Meyering]

[cc'ing bug-automake, in case this is a bug.
 I was using both automake-1.9b and the latest from cvs. ]

This problem may be due to the convoluted way in which coreutils
bootstraps into a hierarchy under .#bootmp, and then moves the
files into ./lib and ./m4.  See below for details.

        * jm-macros.m4 (gl_MACROS): Remove use of AC_CONFIG_LIBOBJ_DIR(lib).
        It is no longer needed, and was causing dependencies to appear
        in lib/lib/.deps, which provoked a "make distcheck" failure.

As I said, the problem was that config.status created (and populated)
lib/lib/.deps.  But it did only what automake told it to do.
automake generated lib/Makefile.in containing these lines.  Notice
how everything down to         "include .deps/xstrtoumax.Po" looks fine.
But then there's an extra lib/ "include lib/.deps/xstrtoumax.Po"
