Proposed "fix"

Using CMake started under an MSYS environment and using MSYS makefiles with
MinGW-w64 incorrectly identifies the host and default target as
"i686-pc-mingw32" instead of "x86_64-w64-mingw32".

This behaviour is down to line 11 in cmake/modules/GetHostTriple.cmake, which
checks for MSYS when I believe the correct behaviour would be to ignore it. I,
at least, have had no problems compiling and building after removing the check.
I may have not considered the original reason for adding the check in the first
place, but either way I don't believe it is correct as it currently is.</pre>
