[PATCH, Android] Stack protector enabling for Android target

[Igor Zamyatin]

Hi!

The patch enables stack protector for Android.
Android targets don't contain necessary information in features.h so
we explicitly enable stack protector for Android.

Bootstrapped and regtested on x86_64. Ok to commit?

Thanks,
Igor
