Good news!  Now that --disable-neon-support works, the Android build is
passing all of the tests except for libgcrypt/random, which hangs on that
prefer-fips-rng test, and libassuan/fdpassing, which I am not sure is needed
on Android.  Also, the gnupg/tests are not run because they require a UNIX
shell environment which Android does not have (things like /usr/bin/test,
/usr/bin/[, etc)
