Toolchain from gcc-termux. Removed termux dependency, but may still depend on android-5
Do not use it to build hardfloat binaries without android sysroot (https://github.com/FWGS/xash3d-android-tools-sysroot)
It will link output files with system libraries, so without sysroot it is very depended on your system. BTW, sysroot will disable libgnustl_shared dependency
To enable STL or RTTI support use STLPort (https://github.com/FWGS/xash3d-android-tools-stlport)
This is untested with android 4.x and should not work with 2.x-
