user-native-test-5

This is for testing user natives, which also includes FFI support.

The name format is "r3-core-${OS_ID}-${GIT-COMMIT}-${BUILD_TYPE}-CPP${AS_CPP}.zip

where OS_ID is given as:

	x86	x86_64
Windows	0.3.1	0.3.40
Linux	0.4.4	0.4.40
OSX	0.2.5	0.2.40

AS_CPP = 1 means the binary is built as C++.

user-native-test-4: Build 32-bit version binaries correctly

Changing OS_ID is not enough.

user-native-test-3: Support cross-compiling for windows using cmake

When building with TCC, it needs to be a cross-compiler, and
present as ${CMAKE_CURRENT_BINARY_DIR}/cross-tcc

To compile for 64-bit windows:
$mkdir build
$cd build
$cmake ../make -DR3_OS_ID=0.3.40 -DCMAKE_TOOLCHAIN_FILE=../make/Toolchain-cross-mingw64-linux.cmake

user-native-test-2

Zip r3-core and libtcc1.a for uploading

user-native-test-1: Set extra compile flags for clang

To eliminate some warnings

user-native-test0

Just for user native testing
