Move the shared library construction stuff to Makefile.shared, a

helper makefile that generalises our way of building shared libraries
and is designed to take care of almost anything (I hope).

+#
+# Helper makefile to link shared libraries in a portable way.
+# This is much simpler than libtool, and hopefully not too error-prone.
+#
+# The following variables need to be set on the command line to build
+# properly
+
+# CC contains the current compiler.  This one MUST be defined
+CC=cc
+# LDFLAGS contains flags to be used when the temporary object file is
+# created.  SHARED_LDFLAGS contains flags to be used when the shared
+# library is created.
+LDFLAGS=
+SHARED_LDFLAGS=
+
+# LIBNAME contains just the name of thhe library, without prefix ("lib"
+# on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
+# .dll, ...).  This one MUST have a value when using this makefile.
+# For example, to build libfoo.so, you need to do the following:
+#LIBNAME=foo
+LIBNAME=
+
+# LIBEXTRAS contains extra modules to link together with the library.
+# For example, if a seond library, say libbar.a needs to be linked into
+# libfoo.so, you need to do the following:
+#LIBEXTRAS=libbar.a
+# Note that this MUST be used when using the link_o targets, to hold the
+# names of all object files that go into the target library.
+LIBEXTRAS=
+
+# LIBVERSION contains the current version of the library.
+# For example, to build libfoo.so.1.2, you need to do the following:
+#LIBVERSION=1.2
+LIBVERSION=
+
+# LIBCOMPATVERSIONS contains the compatibility versions (a list) of
+# the library.  They MUST be in decreasing order.
+# For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
+# and libfoo.so.1, you need to do the following:
+#LIBCOMPATVERSIONS=1.2 1
+# Note that on systems that use sonames, the last number will appear as
+# part of it.
+# It's also possible, for systems that support it (Tru64, for example),
+# to add extra compatibility info with more precision, by adding a second
+# list of versions, separated from the first with a semicolon, like this:
+#LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
+LIBCOMPATVERSIONS=
+
+# LIBDEPS contains all the flags necessary to cover all necessary
+# dependencies to other libraries.
+LIBDEPS=
