[gdb 19981224] Enable linking gdb against shared libbfd

[Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>]

The following patch is a first shot at linking gdb 19981224 against a
shared libbfd (tried on IRIX 6.2).  It has a couple of shortcomings:

* libtool support was added manually to gdb/Makefile.in.  It currently
  lacks the libtool clean targets usually generated by automake's libtool
  support.  This will happen naturally once the gdb Makefile is converted
  to use automake.

* Using a shared libbfd isn't currently very useful since it doesn't
  support proper (in the libtool sense) interface versioning, without
  -release $(VERSION).  Since any release of binutils and gdb comes with
  it's own version of libbfd, there cannot happen any sharing, at least not
  between binutils and gdb.  Are there any plans to convert libbfd to
  proper versioning?  I doubt it is easy, if at all possible, given it's
  constant state of flux.

	* Makefile.in (LIBTOOL): Add.
	(CC_LD, install_only): Invoke $(LIBTOOL) here.
	(BFD, OPCODES): Reference libtool libraries to drag in shared
	versions if present.
	(INSTALLED_LIBS, CLIBS, CDEPS): Link -lopcodes first, it depends on
	-lbfd.

	* gdb/configure.in (AM_PROG_LIBTOOL): Invoke.
