Currently Android does not have posix_spawn, thus posixmodule.c does not build. Build log attached. I'll create a patch for this.

Testing environment: my building scripts [1] + Android NDK r16b
Building target: ARM64, android-21

/cc Primary reviewer of bpo-20104 and Android enthusiasts in CPython

PS. Looks like posix_spawn will be available in Android P (API 28) [2]. For now I propose to disable it in CPython.

With #5418 merged, I guess this issue can be closed?

likely. i don't have an android build, please reopen if there are still android posix_spawn related build issues.
