[committed] trivial boehm-gc configury cleanups

[neroden at fastmail dot fm (Nathanael Nerode)]

Built/checked i686-linux, committed.

2004-08-16  Nathanael Nerode  <neroden@gcc.gnu.org>

	* aclocal.m4: Remove obsolete construct for old automake.
	* acinclude.m4: Regenerate with aclocal 1.9.1.
	* configure.ac:  Remove duplicate AC_WITH calls.  Replace
	AC_CANONICAL_SYSTEM with AC_CANONICAL_HOST, AC_CANONICAL_TARGET.
	Replace _GCC_TOPLEV_NONCANONICAL calls with ACX_NONCANONICAL_TARGET.
	Remove now-redundant subst of target_noncanonical.  Remove
	now-gratuitous m4 quoting around $.  Replace AM_PROG_LIBTOOL with
	AC_PROG_LIBTOOL and remove second, redundant AC_PROG_LIBTOOL.
	Use slightly more modern form of AC_INIT.
	* configure: Rebuild with autoconf 2.59.
	* Makefile.in, include/Makefile.in: Rebuild with automake 1.9.1.
