Through using ndk-build, -Wno-unused-command-line-argument is passed in
somewhere in the pipeline and hides this warning.
The warning can be turned on with:
APP_CPPFLAGS := -Wunused-command-line-argument ...
and then when building, you can see:
C/C++: clang++: warning: argument unused during compilation: '-mfloat-abi=softfp' [-Wunused-command-line-argument]
C/C++: clang++: warning: argument unused during compilation: '-mfpu=neon' [-Wunused-command-line-argument]
C/C++: clang++: warning: argument unused during compilation: '-maes' [-Wunused-command-line-argument]
These are unused because both floating-point and NEON are required in
all standard ARMv8 implementations. [1] [2]

Since NDKr15 (released 2017), unified headers are used by default [1]
Remove -isystem option that was passing bad values to command-line.
The actual value being passed to command-line was:
```
-isystem DK/sysroot/usr/include/RIPLE
```
because of using $NDK and $TRIPLE instead of $(NDK) and $(TRIPLE)
But regardless, $NDK and $TRIPLE were never actually defined values and were just
place-holders mentioned in [1]

Surface Addresses are the addresses that
the roots report back to you.
This is helpful for trouble shooting.
If you're behind NAT, the source port is different
than what zerotier is bound to.
If the list of surface address ports is larger than the list of
bound addresses, you are probably behind symmetric NAT.
Anways this can be added to later with a more simple
"easy" or "hard" nat computed message somewhere.
