New:

* Added support for TAPIv3 stubs (including "zippering" target)
* Added support for MacOSX SDKs up to 10.14
* Added new SDK packaging script for SDKs that end with ".xip" (tools/gen_sdk_package_pbzx.sh <xcode.xip>) (tested up to Xcode 10.2.1)
* Updated cctools to 921 and ld64 to 409.12

Fixed:
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/171
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/178
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/182

Changed:
* cctools, ld64, apple-libtapi and xar are now "git clone"'d and no longer come with OSXCross.

Removed:
* Support for Cygwin and *BSD (besides FreeBSD)
* Support for building OSXCross with GCC

-## STEP BY STEP INSTALLATION GUIDE: ##
-
-#### Step 1: ####
-
-Get [Cygwin](https://cygwin.com):
-
-32-Bit: https://cygwin.com/setup-x86.exe  
-64-Bit: https://cygwin.com/setup-x86_64.exe
-
-Note: *You can compile for 64-bit in a 32-bit environment.*
-
-Click on setup-*.exe and install the following packages:
-
-`git`, `make`, `clang`, `gcc-core`, `gcc-objc`, `gcc-g++`,  
-`patch`, `wget`, `libuuid-devel`, `openssl` and `pkg-config`
-
-For LTO support you will also need:
-
-`libllvm-devel`, `libllvm`, `libedit` and `libffi`
-
-The Cygwin package of libLLVM lacks the LTO library, but you can create that dll
-by issuing the following command:
-
-`./tools/gen_cyglto_dll.sh`
-
-#### Step 2: ####
-
-Open the Cygwin shell:
-
-![](images/cygwin/osxcross/2.png)
-
-#### Step 3: ####
-
-Clone the OSXCross repository:
-
-![](images/cygwin/osxcross/3.png)
-
-#### Step 4: ####
-
-Get the Mac OS X SDK and move it into  
-`C:\Cygwin*\home\<User>\osxcross\tarballs`.
-
-Please see [README](README.md) for more.
-
-#### Step 5: ####
-
-Build OSXCross:
-
-![](images/cygwin/osxcross/5_1.png)
-
-![](images/cygwin/osxcross/5_2.png)
-
-#### Step 6: ####
-
-Add the printed target/bin path to your `~/.bashrc`:
-

-
-#### Step 7: ####
-
-Restart the Cygwin shell:
-

-
-#### Step 8: ####
-
-Verify target/bin is in PATH:
