[PATCH] Update bfd to autoconf 2.5x, take 2

[Nathanael Nerode]

This performs the minimal update to autoconf 2.59 for bfd; another important
step in updating the whole of src to 2.59.  This is the revised version,
which actually handles bfd install correctly.

Built on i686-pc-linux-gnu with no serious differences in generated files.

There are most definitely further cleanups which I might make later.

OK to commit?

	* acinclude.m4: Require AC_CANONICAL_TARGET, not AC_CANONICAL_SYSTEM.
	Include ../config/acx.m4 and use ACX_NONCANONICAL_* where appropriate;
	replace uses of *_alias with *_noncanonical.
	* aclocal.m4: Rebuild with aclocal 1.4p6.
	* Makefile.in: Rebuild with automake 1.4p6.
	* doc/Makefile.in: Rebuild with automake 1.4p6.
	* configure.in: Autoupdate with autoupdate 2.59.
	* config.in: Regenerate with autoheader 2.59.
	* configure: Regnerate with autoconf 2.59.
