So unfortunately, the Android gnulib porting effort didn't go very far.
And it still doesn't build.  It seems like this is currently a deal
breaker for gnupg on Android since there doesn't seem to be interest in
the gnulib maintainers in fixing it for Android, and gnupg's include
gnulib is a custom version, so the upstream fixes might not even apply
to gnupg.

What is the next step?
