The error messages suggests it is the former, you need to integrate
gnulib in the documented way otherwise there will be many strange
compiler errors.  I don't recall any significant discussions involving
Android as a porting target, but I think that is mostly because of lack
of testers not that it is intentionally not supported.

I could help with the gnulib infrastructure in GnuPG if you want, I
think there is good opportunitity to reduce code duplication.

The first thing to do for Android would be to build a gnulib mega
tarball for the environment -- that way we'll identify any gnulib bugs
immediately.  Running the extensive set of self checks will also be
quite interesting, implementing a POSIX system is not easy.  Doing this
would be quite interesting.  Where do I find a android cross-compiler?
