[PATCH] Android target support (as part of LLDB build)

[Vince Harron]

Why are you using the __ANDROID_NDK__ define?  I think we should use __ANDROID__ instead.  If it's not defined in out build, we should define it (instead of __ANDROID_NDK__)

I've checked Android NDK versions 3, 9, and 21 and all of them automatically have these symbols defined when building with Android.mk

__ANDROID__
ANDROID

vharron at tifa:~/dev/defines$ cat jni/main.c
#include <stdio.h>

int
main() {

#ifdef __ANDROID__
  printf("__ANDROID__\n");
#endif
#ifdef ANDROID
  printf("ANDROID\n");
#endif
#ifdef __ANDROID_NDK__
  printf("__ANDROID_NDK__\n");
#endif

}
