The libfdt shared library is only installed by its unversioned name.
Including it properly in a distribution requires installation of both
the versioned name (used in the binary-only package) and the unversioned
name (used in the development package). The latter is just a symbolic
link, so you need to change the soname in turn to include the version.
While at it, use Makefile variables to shorten some lines and avoid
cut-and-paste typos; and clean up remnants of when shared libraries were
not supported on Darwin.

Build a libfdt shared library in addition to the existing .a that is
created. Symbol versioning is used from the libfdt/version.lds script.

The definition of LIBFDT_INCLUDES was accidentally dropped.
Put it back and add srcdir prefix handling for it.

Currently the Makefile.dtc and Makefile.libfdt fragments include a
number of things that seemed like they might be useful for other
projects embedding the pieces, or for a make dist target.
Well, we have no make dist target, it's become fairly unclear that
these things would actually be useful to embedders (the kernel
certainly doesn't use them), and it's a bunch of stuff with no current
users.
This patch, therefore, removes a bunch of unused definitions from the
Makefile fragments. It also removes a dependency declared in
Makefile.libfdt (of libfdt.a on the constituent .o files) which was
incorrect (wrong path), and if corrected would be redundant with the
similar dependency in the top-level makefile.

This patch makes a number of Makefile cleanups and improvements:
- We use more generic rules to invoke flex and bison, which is
useful for some of the other changes.
- We use the name dtc-lexer.lex.c for the flex output, instead
of the default lex.yy.c. That means less potential for confusion if
dtc is embedded into other projects (e.g. the kernel).
- We separate out a Makefile.dtc designed for embedding into
other projects, analagous to Makefile.libfdt.
- Makefile.libfdt is cleaned up to be more useful based on
some actual trial runs of embedding libfdt in the kernel bootwrapper.
- Versioning related rules and variables are collected into
one place in the Makefile.

This patch makes various improvements to dtc's make install target:
- libfdt is also installed. Specifically, libfdt.a and the
two export relevant header files, fdt.h and libfdt.h are installed.
- ftdump is no longer installed. It was only ever a
development debugging tool and may well go away at some point.
- In keeping with normal conventions, there is now a PREFIX
variable, allowing control of where things are installed (in /usr,
/usr/local, /opt, etc.).
- By default, installed into the user's home directory,
instead of /usr. This is friendlier for self-installers, package
builders can easily override PREFIX to restore the old behaviour.

This patch substantially revamps the dtc Makefiles, in particular
better integrating the Makefile for dtc proper with the Makefiles
imported from libfdt for libfdt and the shared testsuite. Notable
changes:
- No recursive make calls. Instead subsidiary Makefiles are
included into the top-level Makefile so we get a complete dependency
information.
- Common pattern rules, CFLAGS etc. shared between dtc, libfdt
and testsuite, rather than separate copies.
- Vaguely Kbuild-like non-verbose mode used by default, which
makes warnings more prominent.
- libfdt Makefile consists only of variable definitions and
helper rules, to make it more easily embeddable into other Makefile
systems.
