No problem Douglas! This is pull request enables two somewhat separate features (ARMv8 (cross)compilation and Android compilation). Both parts are a bit tricky to test properly in this case. The ARM part requires ARM environment to run, which can be problematic due absence of proper support. As for the Android part, it looks like Travis requires gradle and there is no apparent support for NDK.
However both can be (and were) cross-compiled from a normal Linux box. Android may require NDK toolchain though. The only real difference that I came across when compiling C for Android is the lack of
stderr and the mandatory
-pie flag to run the executable.
