Subject: Bug 1417 - Android: Add ANDROID_TOOLCHAIN_SYSROOT1_INC_STL for LLVM's
 C++ STL headers (default since NDK r18)

Using LLVM's c++_shared as of NDK r18: https://developer.android.com/ndk/guides/cpp-support.html
LLVM's c++ headers must come before other system header!
Also see https://github.com/android/ndk/issues/452 and https://gitlab.kitware.com/cmake/cmake/issues/17059

Also adapt make/lib/gluegen-cpptask-android* files:
- Compiler
-- align for potential C++ usage, i.e.:
-- don't use '-sysroot' not '-isysroot'
-- IF using C++ STL, prepend ANDROID_TOOLCHAIN_SYSROOT1_INC_STL
-- just add normal sysroot headers via '-isystem'

- Linker
-- Use ANDROID_TOOLCHAIN_SYSROOT1_LIB1 and ANDROID_TOOLCHAIN_SYSROOT1_LIB2 for '-L' search path
-- where ANDROID_TOOLCHAIN_SYSROOT1_LIB2 is for 'libc++' -> 'c++_shared'
