John Lin fbdb2093dd Fix Android build errors on macOS.

- Add sysroot path to environment variable 'CPPFLAGS':
  When checking C preprocessor, the 'configure' script of libbacktrace uses 'CPPFLAGS' rather than 'CFLAGS' and doesn't get the correct search path. (#15758)
  This check passes on Linux because the '/lib/cpp' fallback is available there.

- Introduce CMake toolchain file for Android cross compiling:
  CMake needs several variables [1] to cross compile for Android.
  It works (accidentally) on Linux because cmake-rs sets compilers correctly and binutils for Linux & Android are pretty much the same.
