Makefile: Rename TARGET_DIRS to TARGET_LIST 
To be more accurate on its purpose and make code that looks for a certain
target out of this variable more readable.

Unicorn-Engine MSVC Native Port Notes
Zak Escano - January 2017
These notes are to help myself and others with the upkeep of the msvc native port
of unicorn-engine.
:: Build settings
Visual Studio Version: Visual Studio 2012 v11.061219.00 Update 5
Platform Toolset: Visual Studio 2012 - Windows XP (v110_xp)
Character Set: Use Multi-Byte Character Set
Runtime Library Debug: Multi-threaded Debug (/MTd)
Runtime Library Release: Multi-threaded (/MT)
Precompiled Header: Not Using Precompiled Headers
Additional Options: /wd4018 /wd4244 /wd4267
:: Changes porting unicorn from GNU/GCC to MSVC.
There were many many many changes to make this also build in MSVC
while still retaining the ability to build in GNU/GCC.
Most were due to either GCC specific things or MSVC lack of decent
standard C support especially in VS2012. Also some were for
posix/platform specific stuff that is not present in windows.
Some of the more common changes were:
* Compatibility for GCC style __attribute__'s.
* Change GCC switch case ranges to specify every case individually, ie:
"case 1 ... 3:" changes to "case 1: case 2: case 3:"
* Change GCC struct member initialisation to the more generic
initialisation of all members in order, ie:
{ .value = 1, .stuff = 2 } to { 1, 2 }
* Remove GCC style macro return values which MSVC does not support, ie:
#define RETURN_ONE(x) ({ some stuff; (void)1; })
* Compatibility for posix headers that are missing in windows, ie:
stdbool.h, stdint.h, sys/time.h, unistd.h
:: CPU specific libraries
The gnu/gcc way of building the qemu portion of unicorn-engine involves makefile magic
that builds the same set of sourcecode files multiple times. They are built once for each
supported CPU type and force "#include" a CPU specific header file to re-"#define"
function and variable names that would otherwise be the same for each build.
These multiple builds of the same files are then all linked together to form
the unicorn library.
As an example when building for "x86_64" cpu type the generated header file "x86_64.h"
is force included and it contains a bunch of defines such as:
#define phys_mem_clean phys_mem_clean_x86_64
So you can see that it adds the cpu type on to the end of each name in order
to keep the names unique over the multiple builds.
The way I handle this in MSVC is to build a seperate cpu specific library, containing
this set of repeatedly used sourcecode files, for each supported cpu type.
These cpu specific libraries are then linked together to build the unicorn library.
For each supported CPU type
* Each CPU specific lib has a "forced include" file specified at:
Configuration Properties -> C/C++ -> Advanced -> Forced Include File
so for x86-64 this is "the file "x86_64.h" which is a generated file.
:: Other things
* The Qemu code for GNU/GCC seems to rely on __i386__ or __x86_64__ defined if
the host is 32bit or 64bit respectively.
So when building 32bit libs in msvc we define __i386__.
And when building 64bit libs in msvc we define __x86_64__.
* There is a tcg-target.c for each target that is included into tcg.c.
This is done using "#include tcg-target.c"
It is NOT built separately as part of the *.c files for the project.
:: Info from makefiles
This info is compiled here together to help with deciding on the build settings to use.
It may or may not be of use to anyone in the future once this all builds ok :)
