Subject: [PATCH] windows: document MinGW zlib install and remove custom zlib
 search

In 5580d200d7ae49cdb4f30913e3ef2d74e431ff60 ("appveyor: install zlib and minor
clean ups") I found AppVeyor builds could use a pre-built, statically linkable
zlib from Cygwin/MinGW.

Document the MinGW zlib packages in the README and remove the custom Windows
zlib searching from the configure script.

 How to compile fio on 64-bit Windows:
 
  1. Install Cygwin (http://www.cygwin.com/). Install **make** and all
-    packages starting with **mingw64-i686** and **mingw64-x86_64**.
+    packages starting with **mingw64-i686** and **mingw64-x86_64**. Ensure
+    **mingw64-i686-zlib** and **mingw64-x86_64-zlib** are installed if you wish
+    to enable fio's log compression functionality.
  2. Open the Cygwin Terminal.
  3. Go to the fio directory (source files).
  4. Run ``make clean && make -j``.
